It definitely wasn't the best Disney On Ice production I've seen, but my 5 year old cousin loved it. Each kid was giving a rubber bracelet with two buttons and a light on it (Similar to Syndrome's remote in the movie only read with The Incredibles on it).
At the end of the show, the bracelets all activated and the children were instructed to push certain buttons to do certain things and interact with the show. This happened about 2 or 3 times towards the later part of the show, and the kids really ate it up
The kids (especially young boys) will love it, for us Disneyland buffs, only the Haunted Mansion segment is memorable.
