The Purge

In an America wracked by crime and overcrowded prisons, the government has sanctioned an annual 12-hour period in which any and all criminal activity—including murder—becomes legal. The police can't be called. Hospitals suspend help. It's one night when the citizenry regulates itself without thought of punishment. On this night plagued by violence and an epidemic of crime, one family wrestles with the decision of who they will become when a stranger comes knocking.  When an intruder breaks into James Sandin’s (Ethan Hawke) gated community during the yearly lockdown, he begins a sequence of events that threatens to tear a family apart. Now, it is up to James, his wife, Mary (Lena Headey), and their kids to make it through the night without turning into the monsters from whom they hide.

This was one of the cleverest (albeit creepy) premises for a "horror" movie in a while.  I remember thinking holy $hit when I first saw the trailer.  The movie definitely delivered on the premise.  This was not just a horror movie.  It had very heavy political/psychological themes throughout that at times worked out awesomely with the scary parts but at other times (unfortunately towards the end of the movie) kind of held the movie back from committing one way or the other.  Not sure if that makes sense.  At times you were totally engrossed in the political/psychological stuff but at others you were totally wrapped up in the defend your house/family at any costs angle and you just wanted it to be a straight up payback type of movie.  I can't really go into too much more detail without blatantly telling you what happens but I was a little put off by the end of the movie because I had chosen in my head what way I wanted the movie to go and it didn't go that way. 

I would definitely recommend anyone who was intrigued by the trailer going to check out this movie.  I did enjoy it very much even though I didn't like the last 5-10 minutes.  There was good creepyness and covered all the different angles of looking at the situation that the premise presented evenly.
