Yeah i'd like to know more about the demon thing, seems like an interesting chap.
But i didn't much like the 1st one, it was good, but it wasn't great and i have yet to see the 2nd one, but i intend to once it opens in the theatres.
It shouldn't be a series, it isn't much different from the other recent horror movies, except they have a cool villian, thats about it.
