So many issues, but I'll start with my major gripes:
1) Mediocre acting.
2) Unlikable characters.
3) Unrealistic reactions from the characters.
- Picture this: you're in your sister's home. Someone keeps turning the kitchen tap on. The lights go out and you clearly hear footsteps from upstairs. Do you a) run straight out the front door or b) go upstairs to investigate? Yep, this character picks option b.
- The lead female character goes through a traumatic series of events in her own house, but she kicks out her boyfriend and stays in the house. Dumb.
4) Plot holes. I can't even be bothered with a list.
I don't know how long the sister had been dead when the boyfriend got into bed with her corpse, but he would smell the body way before he got into bed with it.
Appallingly stupid movie and it's a shame, because the bones of a good story were there. 1 star plus 1 for keeping me watching til the end.
