I got the Art of Tangled and the Art of Megamind this week, and both of these books are awesome! The Art of Tangled is worth the money for Glen Keane's sketches ALONE, never mind all the incredibly beautiful renderings and interesting insight into the design process. If you've got the money, these are both more than worth the price!
I'm looking at the art of Darksiders next but I'm curious if any of you have checked that one out? Thoughts?
