This show is a bit overrated. To me, it has 2 functions:
1) Gets rid of 5,000 people out of the rest of the Studios which cuts the lines down.
2) On certain nights, they do a 2nd show which happens 30 minutes after the place closes. That is nice to be able to extend your day.
The show itself is pretty evil in nature, which is why it bugs me. Yeah, Mickey defeats evil in the end, but it is a pretty dark show.
