We were taking my 3.5 year old nephew to his cousin's house (over an hour drive) so my teen DD popped Wall-E into her portable DVD. He had told her he saw the movie with his dad when it came out, a long time ago.
When the sad little musical number started playing in the beginning, I said from the front seat, "Aw, Wall-E's lonely." And my nephew said "He wants his E-EE-V-Uh!"
I was very impressed- this kid hadn't seen the movie in 6 months, which is like, a fifth of his LIFE, and he got the whole thing.
Disney really should put Wall-E into the parks (Epcot is a natural, so is Tomorrowland). But then again, I always say Jungle Book has the best music in all of Disney's storied history, and there's barely a trace of that one anywhere. (Why not the "Jungle Book Cruise"? They could do sing-alongs instead of the lame puns.)
