Disney Addicted I think you are confusing the monters inc ride with the pixar pals show. But then, I didn't see a monsters inc show when we were there. maybe they switched out toy story for monsters in...
Saw the Incredibles and the toy story one when we were there in june. They were cute. It seems like it starts out like a parade so people sit down, but theres a only a few people that move from point a to pint b, stop at b, do a small show, and go back to a and disapeer so those who sit down miss out on a lot. It's alot of guest interation, everyone mostly just stands around in a big clump while the shows go on. In the incredibles they teach the kids (and adults!) how to be superheros. In the toy story on I saw they had everyone do music with the green army men, while they green army men did some pretty cool drum tricks.
It was fun. But they are also very short. If your not there right when they start, there over before you can find a place to see whats going on.
