Collider has compiled a ranking of the 20 best Marvel Cinematic Universe films based on average audience ratings from Letterboxd, the film-focused social media platform. The list is framed as a more grassroots alternative to critic-led aggregators like Rotten Tomatoes, offering a sense of which MCU entries genuinely resonate with everyday viewers across the franchise's long and expansive history.

Among the lower-ranked entries covered, Black Panther: Wakanda Forever (2022) sits at 20th with a 3.3/5.0 rating, praised for its handling of Chadwick Boseman's death and Shuri's character arc under director Ryan Coogler. The Fantastic Four: First Steps (2025) ranks 19th, also on 3.3/5.0, noted for its 1960s retro-futuristic style and Vanessa Kirby's performance as Sue Storm, while Shang-Chi and the Legend of the Ten Rings (2021) takes 18th place with a 3.4/5.0 score, credited partly to stunt work choreographed by Andy Cheng.
