The thing with Rocky Horror is that the original movie is really pretty bad. I mean, if you strip away all the cult stuff that we've all built up around it, it's really a bad movie. I love it, but it's horrible.
So, what do they expect to happen with a remake? Do they really think they can take that story and make it appealing to watch without all the audience participation? Or do they just figure we'll all go see it and do the same things we do with the original? I don't think that's gonna happen.
A remake, in this case, is not a good idea.
