I've only seen Lilo & Stitch acted out on a travelling Disney On Ice show. That was enough for me as I pondered whether I should just yank my kids out of there as I didn't know that Stitch was going to be such a big part of the show. Even as an Ice Show there was belching and bad behavior on display. Plus the themes of losing your parents and acting out because of it were way too much for little kids. It's always nice to see a character change for the better in a movie, but it seems Disney World likes him better as an out of control, disgusting menace. I guess good Stitch is not entertaining enough.
I really don't think Walt Disney himself would be very proud of what they have done with Lilo & Stitch. Disney is simply saying "show me da money". Gross-outs sell these days. Come on lets have an attraction where the audience gets smelly, warm vomit spewed all over them. The kids will love that.
