Best Sci-Fi Movies of the 2020s: Top Picks & Rankings

There’s a moment in every decade when sci-fi stops being just escapism and starts holding up a mirror to the world we’re actually living in. The 2020s have delivered that in spades — from the sand-swept epic of Dune to the time-bending puzzle of Tenet. This guide compares critic scores from Rotten Tomatoes (editorial film guide) with Reddit community favorites to spotlight the decade’s essential sci-fi.

Movies in Collider’s list: 20 · Movies in IMDB list: 8 · Year range covered: 2020–2025

Six movies show up across multiple lists, and one pattern stands out: the divide between what critics celebrate and what audiences love is narrower than you’d expect.

The table below lays out the key data points from each source, showing how the numbers line up across different platforms.

What are the best sci-fi movies of the 2020s?

Top-rated overall picks

• Dune (2021) — Denis Villeneuve’s adaptation of Frank Herbert’s novel is the consensus front-runner across both critic and audience lists. Reddit users on r/flicks (film discussion community) called it the best 2020s sci-fi movie “hands down.”
• Tenet (2020) — Christopher Nolan’s time-inversion thriller appears on IMDb’s (user-voted list) 2020s sci-fi list and is regularly cited in Reddit recommendation threads.
• The Invisible Man (2020) — Sits at 96% on Rotten Tomatoes, earning a spot on Space.com’s (high-scoring sci-fi roundup) list of sci-fi films above 90%.
• Avatar: The Way of Water (2022) — James Cameron’s sequel dominates box office charts and is listed on Wikipedia’s (decade sci-fi film list) as a major 2022 release.

Why these movies stand out

What makes these films consensus picks is not just quality — it’s that each one redefined some aspect of the genre. Dune proved that dense world-building could still draw massive audiences. Tenet pushed narrative complexity to its limit. The Invisible Man showed that a stripped-down thriller could be more terrifying than any CGI spectacle. Reddit’s r/scifi (community forum) threads consistently return to these titles when users ask for must-watch recommendations.

The implication: the decade’s best sci-fi isn’t defined by budget or effects — it’s defined by directorial ambition. Viewers can bet safely on films driven by a singular creative vision.

What are the best sci-fi movies according to Reddit?

Community favorites from r/scifi

• Reddit users on r/flicks (film discussion subreddit) in July 2022 explicitly named Everything Everywhere All at Once, Dune, and Tenet as top choices.
• A March 2025 thread on r/MovieSuggestions (recommendation community) recommended Dune, No One Will Save You, and Annihilation as favorites from 2020–2025.
• A May 2023 discussion on r/scifi (sci-fi community) mentioned Beyond the Infinite Two Minutes, Last and First Men, Neptune Frost, I’m Your Man, and Strawberry Mansion as candidate picks.

Underrated gems mentioned by users

• After Yang (2021) — Kogonada’s quiet meditation on AI and family appears in Reddit threads as a hidden gem that mainstream lists often overlook.
• Vesper (2022) — A Lithuanian-French indie that users on r/scifi (sci-fi community) praised for its original world-building on a modest budget.
• No One Will Save You (2023) — A near-wordless alien-invasion thriller that r/MovieSuggestions (recommendation community) regularly recommends for its bold storytelling.

The catch with Reddit recommendations: they skew toward discovery and novelty. The community values hidden gems as much as blockbusters, which means a film like Beyond the Infinite Two Minutes gets mentioned alongside Dune — a diversity that traditional critic lists rarely match.

What are the best sci-fi movies according to Rotten Tomatoes?

Critically acclaimed titles

• Dune (2021) — Certified Fresh with a high Tomatometer score, featured in Rotten Tomatoes Editorial (essential sci-fi guide) as a pillar of 2020s sci-fi.
• The Invisible Man (2020) — 96% on the Tomatometer, cited by Space.com (high-scoring sci-fi roundup) as one of the best-reviewed genre films of the decade.
• Dune: Part Two (2024) — Certified Fresh, described by Rotten Tomatoes Editorial (2024 year-end guide) as a visually thrilling continuation of Villeneuve’s adaptation.
• LOLA (2023) — 98% on the Tomatometer, appearing in Rotten Tomatoes Editorial (2023 sci-fi/fantasy guide) as a top-rated entry.

Popular streaming picks

• They Cloned Tyrone (2023) — Ranked #2 in Rotten Tomatoes Editorial (2023 sci-fi/fantasy guide), blending sci-fi with social satire.
• The Creator (2023) — Gareth Edwards’ AI-war epic made the Rotten Tomatoes Editorial (2023 sci-fi/fantasy guide) list, indicating continued studio-scale sci-fi prominence.

The trade-off: Rotten Tomatoes lists reflect critic consensus, while Reddit threads capture the messy, passionate chaos of real fandom. Neither is wrong — they just serve different purposes. For a balanced view, compare the two.

What are the best sci-fi movies from 2020 to 2024?

Year-by-year highlights

• 2020: Tenet and The Invisible Man — the former pushed theatrical release during the pandemic, the latter proved high-concept horror-sci-fi could thrive. IMDb (2020s sci-fi list) includes both as early-decade entries.
• 2021: Dune and The Matrix Resurrections — Dune became the critical darling of the decade, while The Matrix Resurrections divided audiences. Reddit r/flicks (film discussion) threads from 2022 already listed Dune as a top pick.
• 2022: Avatar: The Way of Water and Prey — blockbuster sci-fi dominated. Reddit r/MovieSuggestions (recommendation community) threads from 2025 still reference Prey as a standout.
• 2023: The Creator and Oppenheimer (sci-fi biopic) — The Creator made Rotten Tomatoes Editorial (2023 sci-fi/fantasy guide), while Oppenheimer blurred the line between historical drama and sci-fi in its depiction of nuclear consequences.
• 2024: Dune: Part Two and Furiosa — Dune: Part Two earned Certified Fresh status on Rotten Tomatoes Editorial (2024 year-end guide), and Furiosa expanded the Mad Max universe.

Notable releases each year

The pattern across these years: 2020 and 2021 were shaped by the pandemic, with streaming and hybrid releases dominating. 2022 and 2023 saw a return to theatrical blockbusters, and 2024 delivered major sequels that capitalized on the decade’s earlier groundwork. Wikipedia’s (decade sci-fi film list) frames the 2020s as a broad category that includes cross-genre entries, reflecting how sci-fi has become a dominant lens for storytelling across all formats.

The catch: year-by-year lists are inherently provisional. A film like Dune: Part Two may move up in rankings as it ages, while early-pandemic releases like Tenet may gain or lose stature as the decade’s context shifts.

Which sci-fi movies from the 2020s are must-watch?

Essential viewing for genre fans

• Dune (2021) and Dune: Part Two (2024) — the two-part adaptation that Reddit r/flicks (film discussion community) calls the best sci-fi of the decade. Start here.
• Tenet (2020) — polarizing but essential. IMDb (2020s sci-fi list) ranks it near the top, and it’s a conversation starter for any sci-fi fan.
• The Invisible Man (2020) — lean, mean, and at 96% on Rotten Tomatoes, it’s the highest-scoring genre film of the early decade according to Space.com (high-scoring sci-fi roundup).

Hidden gems you might have missed

• After Yang (2021) — a quiet, philosophical exploration of AI and memory. Reddit r/scifi (sci-fi community) users recommend it as a thoughtful alternative to action-heavy sci-fi.
• Vesper (2022) — a Lithuanian-French indie that builds a rich post-apocalyptic world on a fraction of a blockbuster budget. Mentioned in Reddit r/scifi discussion threads as a hidden gem.
• No One Will Save You (2023) — a near-wordless alien-invasion thriller that Reddit r/MovieSuggestions (recommendation community) calls one of the most original sci-fi films in years.

Why this matters: the must-watch list for the 2020s isn’t just about quality — it’s about diversity of experience. The decade’s best sci-fi ranges from billion-dollar blockbusters to micro-budget indies, and each offers something the other cannot.

The 2020s have already delivered a remarkable range of science fiction — from the sand dunes of Arrakis to the quiet corners of indie cinema. For the sci-fi fan trying to decide what to watch next, the choice is clear: start with the consensus picks (Dune, Tenet, The Invisible Man), then explore the hidden gems that Reddit communities champion. For the casual viewer, the safest bet is any film that earned Certified Fresh status on Rotten Tomatoes — but don’t ignore the threads where passionate fans argue for the weird, the small, and the overlooked.
