Monsters Inc. as a great movie, even from Pixar's high standards. And while I do think this movie is generally underrated as a Pixar classic, it's also far from their best work. In terms of story and characters, this movie is great. Mike and Sully are really good main characters, and the villain and most other side characters and all great too. The story has some good and earned plot twists that make the movie a lot better. The soundtrack has one notable classic tune, and it's a real good one. The visuals, while good, don't really hold up today compared to other Pixar movies, but they're still very good and will stay that way for a while. The comedy is pretty good too, although this movie isn't super hilarious. I think it's easy to forget Monsters Inc., but it's easily one of Pixar's best movies.
