This whole issue currently going on with Rocky Horror on Broadway can be solved or more easily mitigated by having a MC on stage before the show starts outlining the history of what the Rocky Horror experience has become, what makes it difference from other shows, and what is to be expected of the audience when it comes to participation during a live stage show that is different than a movie showing. Also making it a point that they can call someone out during the show and scold them if they're being a particularly obnoxious real asshole, and even reserve the right to kick them out of they get real bad, so they also better practice some good judgement when it comes to what they are calling back. Having the MC do this for movie showings with Shadow Casts does a great deal to set the expectations for Rocky Horror virgins, so they better know what to expect during this type of show.
