It wouldn't be to me. I was somewhere that I didn't have a choice once and saw most of Doubtfire. Aside from music, I'm largely disconnected from pop culture and have never been to the opening day of anything. Musicals make me want to vomit. I've not seen any of the newer Star Wars and NEVER seen Rocky Horror and won't! I'm into subtle and the story and characters, no slapstick or cross dressing entertainment for me.
why wouldn't you?
I don't like slapstick either.. RHPS isn't slapstick, it's an experience... I wouldn't tell anyone to see it without the audience participation though, because that's what it's all about.. as for 'no slapstick/cross dressing' well, you'll miss some amazing movies with that kind of prejudice..Some like it Hot,Psycho,Victor/Victoria, Tootsie,and the Birdcage just to name a few...
but it sounds like you're more afraid you might like it in the pants, rather than you are just too good to see something like that..
