I had no expectations going into this one. I knew it had something to do with a mirror, I hadn't seen a horror film in theaters since Paranormal Activity: The Marked Ones, which left a bad taste in my mouth.
It's not spoiling anything by saying that the film is about two siblings who try to destroy a mirror because of the misfortune that same mirror caused them when they were children.
I really, really liked the concept, the plot, and even some of the writing. The gimmick of them constantly flashing back and forth between the past and present, it worked really well I thought. The editing and the cinematography was really well done. They accomplished a lot given this doesn't have any big name actors, don't have very many genuine scares, and that they don't necessarily do a lot that hasn't been done before.
That said, the acting is completely horrible by the siblings in their "present-day," iteration. It's amazing how much better the kids are at acting than the actual "adults," in the film. Both of the kids were great, and did very well in the action scenes. Complete polar opposites between the kids and the adults in terms of believability.
There aren't really too many plot twists, and the film ends pretty much how any logical person would think it would, but it still was quite entertaining, and even a little bit tense at times. This is definitely a film that over-achieved, and wouldn't mind seeing it turn into a series.
Though, the more I think about it, none of the horror film series that turned into franchises have worked out very well.
Saw? Great. It's sequels? Nothing to write home about.
Insidious? Phenomenal. The lone sequel? Pretty bad.
The Purge? Really unique idea. Verdict is TBD there.
