At the moment, the film holds a 72% score on Rotten Tomatoes. Here is what different critics are saying about Eternals. The Guardian "One of the strengths of the MCU to date is how it has taken time to define each character individually and laid out the grand narratives over successive movies, building a sense of momentum. Here, it's all thrown at us at once. It's like coming into Avengers: Endgame cold without having seen any of the preceding instalments. Most mortals will simply find it too much. Bigger isn't always better." - Steve Rose ComicBook.com "Eternals will likely be one of the more divisive films in the Marvel Cinematic Universe. The strong characters and visuals will be enough for some fans to consider it one of the best of the franchise while others will find its messy plot and extended runtime a hard pill to swallow. No matter how you feel about Eternals, there's no denying Phase Four is off to an exciting start." - Jamie Jirak CNN "Granted, the beauty of Marvel's interlocking universe is that by playing the long game the pieces build upon each other, so that appraisal might change as the next phase comes fully into shape. Eternals certainly doesn't lack for ambition, but for now, Marvel -- emboldened by its success -- has reached for the stars without quite getting there." - Brian Lowry Forbes "More than any previous MCU movie, Eternals feels like "just a superhero movie" and a "we're running out of characters" movie." - Scott Mendelson Flick Fan Nation "This film is massive on every level, both with its story and scale. At times, the narrative can come across as a bit messy, but its heart always shines through. Zhao has crafted something so different from the rest of the MCU." - Austin Burke Variety "Eternals is a fluid and sometimes bedazzling entertainment I'd place on the next tier, because it never transcends its conventionality and makes you go "Damn!" Maybe next time, Zhao can raise the stakes on the heroic vibes by mixing in a drop of nomad reality." - Owen Gleiberman Conclusion True, the MCU could have used more build-up for Eternals. After all, this is a film that introduces ten superpowered beings and several other key figures. It's perfectly understandable why critics are saying that Eternals feels a little rushed and incoherent. But, at the same time, it's not a bad movie either, most agree that it's right in the middle of MCU movies as far as quality goes.
