If by bad, you mean controversial.
I think one of the big problems with Spring Awakening is that the original morality of the play gets lost and muddled in everything else that's going on. The fact that people have trouble figuring out the so-called "point" is just that issue, which I blame mostly on the fact that they changed an explicit rape to something that can fall between the lines. I always thought it was saying something to the effect of, "this is what happens when we repress our children" -- not that suicide, etc. is the result of sexual discovery, but, of course, that interpretation sort of falls through if it's not rape. They've made a hero of Melchior, which I think is a disservice to what the original play was trying to convey.
