"For all the hype, who has actually SEEN this movie?"
I haven't, but lots of others have. Its grossed over 41 million despite playing in less than half as many theaters of all but one of the other top ten grossing movies currently out. The unfortunate lesson in this is that Hollywood will realize that movies like this can make a good deal of money without a huge investment and will continue to put them out.
I just can't believe normal, heterosexual people would have any interest in this movie at all. I really don't know one person personally who has seen it or who wants to see it. My guess is quite a few homosexuals are seeing it more than once.
