First, let me say that this objectively a bad movie. But, if you enjoy the horror genre (and maybe thriller), it's worth putting on in the background, or when wanting to fall asleep.
The writing and plot is decent enough, and somewhat believable. So I gave this 3 stars for that entertainment value. However, the acting is just so poor that it is hard to feel even remotely concerned for the victims. Almost every actor without fail sounds exactly like they are either reading directly from the script, or they think that acting involves being as camp and over the top as possible.
There are many fight scenes in this movie, and unfortunately all of them look very fake. Punches that don't connect, sound effects that don't match correctly to the cause of the sound, and massive windups that look almost comical when certain weapons are used. Seriously, the person being hit should have been able to just casually step aside half the time.
Overall, this movie had the foundation to be something really great due to a compelling background for the lead actress, and the bf's family as well. But both of those things are only ever vaguely alluded to. The audience is left struggling to care about anyone, and half the time hoping they will all just die and the movie ends.
Do NOT pay to watch this. But if you are really bored or multitasking, its vaguely interesting.
