couch potato

why are there some movies, not necessarily good ones, that cause me to sit down and rewatch, no matter how many times i've seen them before? why?

the skeleton key
the replacements (keanu--'nuf said!)
dawn of the dead (the remake)
never been kissed
the grudge
wolf creek
the hills have eyes (the remake)
plus, basically any other scary film (crappy or otherwise) that i've seen before

is it just me?
