To get the blindingly obvious out of the way first: the acting is awful. It is so incredibly bad that I thought it was meant to be "tongue in cheek," but the longer the film wore on, the more it seemed that this wasn't the case. The "actors" all have the same bland, emotionless attitude, it is so bad I still can't entirely believe it wasn't intentional.
The bad effects, costume and props could be excused if this was either a parody film or a low budget horror where you can still tell an effort was made, but in this case the terrible acting and lazy ending just make the cheap props stand out even more - the whole thing seems careless and lacklustre.
The storyline itself is interesting, the overlapping experiences of the girls intertwining with one another is a nice concept that could have been explored further, but it's like the ending that should have tied it all together is just...absent. It just ends, leaving the whole thing as a poorly executed mess.
I stuck with it because I thought it must just be a really slow burn film with a payoff at the end, but no. Turns out it's just a waste of time. Do yourself a favour, watch something else. Time is irreplaceable, this film certainly is not.
