Not a big fan of standard ghost movies (prefer Lovecraftian style horror) but I'll probably pick up the dvd, since I personally enjoyed Blair Witch a lot.
I like those few and far between horror films that work on your imagination rather than just waving a bloody machete in front of the camera or having a guy in a latex mask or CGI monster jump out and yell 'Boo!'. (unless its a zombie movie of course. In which case sign me up!)
Though from the sound of things, I'd better prepare for a few sleepless nights.
