I can't tell if you're goofing around or being serious here, because this is exactly the sort of criticism that gets thrown at this movie and I don't understand it. There are thousands of ludicrous movies out there, but no one ever mentions those.
When I hear the "it's stupid, it's funny, etc." comments it usually sounds to me like the viewer feels he's got to shrug off some challenge to his masculinity or something — "Naw Bro, that's not the scariest movie EVAR — I laughed through the whole thing."
So what's that about?
