Ali Churchill’s review published on Letterboxd:
I can't believe that I had never seen this film until yesterday! It's one of those films that everyone seems to have watched except me. I have to say that while I thoroughly enjoyed it and felt each emotion, in my opinion it is slightly overrated. The animation was just gorgeous along with a score that ranges from sweet and subtle to big and bold in terms of scale. It was a very beautiful story as well and the lack of dialogue was really effective as I was still able to pick out each emotion these robots were feeling, which is a great use of show-don't-tell.
However, the final act was very disappointing. In the first act, there was pretty much no dialogue at all (except for "WALL-E" and "EVA"), whereas in the third and final act there was a lot of dialogue and it ruined the film a little bit for me. I liked the lack of dialogue; it was like the film gave me no choice but to invest every last bit of attention I had into it, which makes the third act feel small in comparison and just painfully average.
Overall, I very much enjoyed this film but it lost it a bit in the final act. Though I won't spoil it in case you haven't seen it, but there is a scene right near the end that was very emotional that almost redeemed the third act. Would I say it was the best Pixar film? No. Would I say it is a very good film? Yes.
