They've definitely got the writing chops to make the book and score incredible. This could be the new Spamalot, but with a much wider potential audience. It also has the potential to piss off a lot of people. I'll be really interested to see how the Broadway community reacts to it once it's in previews, which will probably be a long way off since they haven't announced a venue or casting yet. As a first forray into stage musicals, this was an odd choice to me. I guess they figure that if they're going to take a property that's not South Park-related to NYC, it may as well be one that'll get a lot of press for being controversial. I can't wait to get more info on this, and to see just how outlandish they go. It can't be any worse than Shrek, anyway... right?
This is great. If it's half as good as Insomnia and Memento, it will be head and shoulders above every other comic book movie. We also need the return of Keaton. Then we need a good villain, even though they're running out of ideas.
