I can't really say. I really loved Pixar when I was a kid and the Toy Story films have a special place in my life but as I got older I kind of lost interest. I just saw trailers for them and kind of thought they looked like they lacked the charm I loved in the earlier Pixar films, but after seeing a lot of them more recently I realised I was very wrong. I found Up was an incredibly powerful and actually a pretty grown up film, not just a kids film which is fun for the adults too. The first 20 minutes or so of that film was heartbreaking.
Although I have to say I didn't really enjoy Ratatouille that much. It was okay, but below par for Pixar. The premise and characters didn't seem particularly inspired to me. The story seemed pretty cliche too.
