I enjoyed it but I wished the humor was a little more go-for-broke.
The sub plot about the girl wanting to stay in the film-within-the-film in order to spend more time with her late "Mom" was a bit of a downer.
Yes, but it's exactly that what makes the film special. It's easy to laugh at an old genre full of stupid movies, but way harder to do it in an affectionate way.
My favourite bits where those with the horny-est camp monitor, especially when they ask her to dance in order to lure the killer.
