I found it really enjoyable and fun to watch. It really does make you jump, laugh and scream. OK its low budget, which means the production isn't so slick in places which makes some aspects a stretch to believe in. But this is a horror which seems to have its leanings to more classic films than modern - and I loved that. It's a bit of a roller coaster ride of spookiness and laughs. It starts of slow and intriguing but stick with it as it starts to chug along nicely from about a third of the way in with horror & jumps galore and doesn't take itself too seriously. I say give it a shot - its strangely compelled me to watch it again - which is more than can be said about a lot of movies I've seen lately.
