I'd have to say it's my fav. Disney musical because it's so different, well Aida is good...but..
Lion King is fun. I am biased because I've seen it so many times, but I really love it. I do think "I just can't wait to be King" is the corniest part of the show, but it's there to entertain kids as well as adults.
The costumes are amazing and the lighting is beautiful. The new songs are great. They did just change a part in the opening of Act 2. It's so amazing to hear the harmonies of the voices,etc.
Ofcourse it has it's stupid parts like any show, but either way you should have a fun time even if you don't care to see it again.
