1) I am elated that New Line Cinema has approached a creative team to write an original movie musical.
2) I am worried and saddened that they want it to be a sequel.
3) Everything came to a resolve at the end of the film. If Waters wanted to continue the story, he had DECADES to do so. New Line Cinema wants to make more money, so the obvious way to do so is bank on an already successful project. This is nothing new -- except this is the first time I can remember since GREASE when a creative team has been approached for a movie musical sequel. (Now in GREASE 2 they found a good way to continue the story -- have mostly brand new characters. But HAIRSPRAY without Tracy, Penny, Edna, Link, Maybelle or Seaweed? I dunno 'bout that).
4) Of course it's very possible that a good film/story can come from this. I just hate the intentions behind the desire.
"The Spectacle has, indeed, an emotional attraction of its own, but, of all the parts, it is the least artistic, and connected least with the art of poetry. For the power of Tragedy, we may be sure, is felt even apart from representation and actors. Besides, the production of spectacular effects depends more on the art of the stage machinist than on that of the poet."
