We saw this, mind you, after a very full day of hiking, fishing, and funning. And I'm very, very old, and just a wee bit short on sleep. So, having said that:
I've heard good things about Ratatouille, and have been looking forward to seeing it with my family. Last night my seven-year-old son, Valerie, and I saw it.
In short, Jonathan loved it, and Valerie and I thought it was just okay. Marvelous animation, as always with Pixar, and some chuckles -- but we actually were a bit bored.
It contains nothing offensive, the rat -- who you'd think would be the least sympathetic character -- is charming, and the music score is clever and provides fitting punctuation.
Apart from that, we just found nothing remarkable about it, unlike the Toy Story movies, The Incredibles, and Monsters, Inc. Victims of high expectations? Possibly. But there you have it.
Soon, maybe I'll tell you what I thought of Evan Almighty.
ADDENDUM: I figured out a major reason why the movie didn't work better for me. It was the human protagonist. My wife, with her wonderful gift for conciseness, said it best: "He's just an idiot." Yep. The other Pixar movies as a rule present 3D sympathetic protagonists. This one doesn't. He's a stumbling, clueless cipher, rescued largely by a rat and a woman, and no wiser for it.
