Prior to watching I heard a lot of bad press on the movie with mixed reviews, and thought it deserved a fair shot. I was happily surprised! Plot is a little lackluster in terms of flow, but the themes, humor, and charm of the movie really helps it shine through. AND, it tries to be unique in a world where sequels/fanservice dominates... So kudos to them for taking a chance!
So, don't always take what you hear on the Internet at face value. If you want an enjoyable Pixar movie to watch with wholesome themes, try Elemental!
