Some wise soul posited that, in the 70's, kids went to movies to see adults have sex. Now, adults go to the movies to see kids at it.
But what of Bridesmaids? I went to see this Sunday night at 10:25, which is weird because I never go to movies, ever. But it was fun! Light-hearted vulgarity. What was weird was how the place was filled with teens and twenty-year olds. I mean, how old is Wiig? 35, maybe? Too lazy to look. And Maya Rudolph is no kid, either. Hmm.
So, I guess the third side of the triangle is "movies where adults look stupid and there is vomiting, which is appealing to all ages, expect the Really Olds, who are home watching Fox News/Evening Shade re-runs [tie]."
