This attraction is a phenominal addition to Epcot, and coming from me (I'm very hard to please) that's saying something.
This attraction, even whithout kids is just incredible.
My wife and I have no kids (we're 25 and 27) and we went and were just smiling the entire time.
Just listening to Crush is cute enough and then to see how the kids interact is amazing. At one point, a little boy ran up to the screen to hug crush and his mom ran up to grab him. Of course, Crush made a comment that completely had the room laughing hysterically.
