This is a film you have already seen many times before. It doesn't always have the same name, but it is the typical cheesy ad lib horror plot.
The killer in this movie is _____ which is suppose to surprise you because _____ appears to know _____ and they would never _____ them. Well as it turns out _____ has somehow wronged ______ and therefore _____ seeks revenge!
In addition to the extremely lazy plot writing, the acting is some of the WORST acting I have seen in any "professional" movie. Honestly, I've seen better acting in porn. I am not making this up. The two lead actors in this film are so terrible that whenever they spoke, I was dumbfounded as to how they ever got their roles. Surely there had to be more competent people for these parts.
The lighting is poorly done as well. The result is that ambient lighting ends up casting these huge GLOWS on the screen. I don't know if they were trying to be artsy, but it's extremely distracting.
Even if you wrote better dialogue, got better actors, and made the plot a bit more elaborate, it wouldn't work. It's simply a BORING film. My girlfriend and I guessed the outcome about 1/3 of the way into the movie. It telegraphs the "plot twist" from miles away.
Avoid this movie unless you can watch it for free. It's not even one of those horror movies that are "so bad it's funny". It's simply a mess...and a boring mess at that.
