A story about a high school student who basically invents a way to swing through the air flawlessly and becomes a vigilante
A story about a group of campers who break into a house and find a book of the dead that calls to the world evil demons
A real life boat that sailed through the ocean and crashed into an iceberg
A logic based video game series about lawyers
These all sound like perfect ideas for musicals
Okay, honestly, I don't think crazy things are necessarily bad things (I do like some of the songs in the Spider-Man musical, most of the songs in the Evil Dead musical, and the Titanic... well I'm going to be in that one.) but they're not good things sometimes either. (the Phoenix Wright musical (though I can't understand it, I can read subtitles) sucks) I think there has to be dedication and a great respect for something when you take the idea of something and mess around with its genetics, you have to know how to respect it and take a cautionary approach with changing things too much.
Also I just watched Limitless... it was a great and fun movie.
