Initial idea of the movie was great, but was barely used

Rating: 6/10 (1 October 2013)

To begin, I am giving this movie a really nice 6.5 out of 10 just because the actors did a reasonably good job.
I think other reviewers are being too critical on the movie. A lot of the reviews weighed the entire movie on the fact that the original premise was essentially neglected, but didn't realize and/or recognize that the acting itself wasn't bad at all and was quite average to say the least.
The movie, in all honesty, was a solid movie. However, the media and ads shouldn't have heavily publicized the premise of the movie as being the one-day legalized purge system. This misled viewers and built up too much anticipation for an enticing premise that (although was used) was not to the viewer's expectations.
The movie should've just showed more than just the family being hunted down. Too much emphasis was placed on the family trying to survive as opposed to trying to actively promote or go against the idea of purging.
Neutrality was probably the main issue with the movie, since viewers would expect to see the premise being thoroughly portrayed by the protagonists, or the protagonists trying hard to combat that very evil.
All in all, I don't think I wasted my time watching the movie. I'm quite open, and understand when some movies don't quite hit the mark. I don't think I would recommend this movie since it's hard to introduce it, but if somebody asked me what it was about, I would tell them about it.
