I thought the last boss battle was really easy except when he grabs Sora and you play Riku for like 5 seconds where you need to save him.
The only time I couldn't do continue with the fight was against the guy with the guitar thing where you have a really short time to kill all those things, that was annoying.
Maybe this conversation would be better for the Gaming forum, is it worth making a new thread?
EDIT: I don't really think the majority of Pixar films are fantastic, in fact only Toy Story really, I don't like Finding Nemo for the record(it was okay at some bits not so much at others).
