We were just looking for a nice place to sit and take a break, when the doors opened. So we went in. Didn't have any expectations, just a short stop on our way to ToT.
My entire family, including my husband, (he doesn't care much for the stage shows in any of the parks) rated the show a 10. It's definitely on the must do list at CA.
Just a small tip: If you are wearing your jacket or coat when you go in, (depending on the time of year), take it off before you sit down. It gets warm in the theater, and you can't stand up during the show and you can't get it off sitting down. The seats are very close together.
