This movie is really bad. And not even funny bad.
Tl;Dr - just don't, it is a waste of your time, no matter how low your standards are
If you want to watch an hour of obnoxious Irish college kids setting up boring horror tropes and then running around the house screeching, this movie is for you. The bad acting once things get "scary" (and it's an hour of no-scare intro first) is the only scary thing about the last half hour of this movie.
Because the first hour just consists of a bunch of generally unlikable "college kids" going down the horror checklist: come upon strange location? Check! Talk about the place's horrifying history? Check! Play with an Ouija board? Check! Visit a graveyard in the dark? Check! Film each other having sex? Check. Because what is a bad horror movie without unnecessary sex and nudity?
Then come the ghosts - finally - after an hour of snooze-worthy buildup. I'd get a chance to find the ghost scary, if it wasn't for the TERRIBLE acting overshadowing it too much to care anymore. Especially the girls are absolutely ridiculous. The overacting is painful to watch. The screeching! To the point where you're pretty sure they'd screech at the top of their lungs even if they were presented with a kitten.
Which brings you to the trope - check - of the helpless females, who try very hard to look even more hopeless than the dopey, too-cool-to-respond boys.
This movie is an insult to anyone spending their time watching it. Do yourself a favour - don't watch it. Even I like the occasional BAD horror movie, but this one is just pathetic.
