OK, I have to be the one who pees in the pool. I didn't like it.
Now I should preface this with I am from California. I've seen the original Fantasmic at
Disneyland. After seeing that show on the Rivers of America, this one is a really poor copy.
If you haven't seen the Disneyland show, I imagine you would like this one.
To me the story was convoluted. The characters were too jumbled and the space was too cramped. Also the climax to me was lame. Mickey holds up a "sparkler sword" and the dragon sinks down whether in shame or embarrasment, I'm not sure.
At Disneyland, the story is tighter, the characters more streamlined, the finale has Mickey actually slaying the dragon (a laser goes from his sword to the dragons chest and they are across from each other instead of one in front of the other) and at the end the characters are all on the huge paddleboat.
We also had a whole group of socially challenged teens behind us that I just wanted to throttle. No parents in sight.
Now I know that MGM has less space, no huge river, no paddleboat. But this was my experience. It's like going to Paris, seeing the Eiffel Tower and then going to Epcots France and seeing theirs.
So if you have never seen the show, go. If you've seen Disneylands, do something else with your night.
