Over the hedge would also be a good one. I personnally thught Kung Fu Panda was a terrible movie (story line anyway) I fell a sleep during it.
I liked the PQ & SQ of Wall-E, but, felt the story line just wasn't there.
Then what did you like so far for the kids?
Two animations that are fine for kids that I've enjoyed are
Surf's Up and
Meet The Robinsons. I didn't list them before because they aren't really reference discs for showing off surround sound. OTOH, the crashing waves in Surf's Up do feel like crashing waves. The waves look
incredible. The movie was purposely done with a grainy look as to mimic a documentary, and it's very successful. The voice cast includes Shia Labeouf, Jeff Bridges, Zooey Deschanel, Jon Heder, James Woods.
Meet The Robinsons has a few pretty funny moments, like the kung fu food fight, and is overall pretty entertaining.
Both have excellent PQ.
Open Season, I don't recommend, as I thought it was pretty lame, though the PQ is probably even better than
Meet The Robinsons.
