I liked it way better than I thought I would! Maybe squeaks into their top ten if you don't count every single Toy Story film.
More How to Train your Dragon than Shrek (both of which are good in their own ways). But all of which is to say the majority of the 'gags' that people have been put off by in the trailers were pretty much all there was in the movie. The rest of the movie is higher brow. In Pixar fashion it actually has quite a lot of heart and a sort of obvious, but touching conclusion.
Pixar now has quite the mature catalogue of movies that help process death, loss, grief and acceptance. This movie in particular I think quite masterfully touched on some pretty heavy topics of how children process these things and can build up a lot of guilt and self-blame.
Definitely not a Good Dinosaur (which felt like they ran out of a story after having committed to animating the whole thing).
Plus, if you have any passing interest in D&D this is basically your movie.
