So The Purge is a bit of a hybrid - we'll call it home-invasion-horror-thriller-social-commentary. And I can tell that it's trying really hard to be all of these things at one time. At actually accomplishing being all of these things to the audience, the movie is a bit of a letdown. There are a lot of interesting questions raised, just not explored in the way I wanted them to be. I also need to point out somewhere (why not here?) about how happy I was to see Lena Headey in a starring role, as I have never seen Game of Thrones. Love this woman. Ethan Hawke is alright, but his character feels like every other character he's ever played so I was a little less impressed.
And I seriously have to mention this: How is the "no emergency services available" thing ANY different from ANY other horror movie out there? When do the cops and ambulances always show up in horror movies? At the end. So this had no effect on me or the story at all.
Was this really a review or did I just rant for a long time? Sorry, but this is all stuff that I've been thinking about since watching the movie and I had to put it down somewhere. I can't fully recommend The Purge because it was completely missing that "wow" factor that I have been desperately seeking in a movie lately, but it's also not a completely horrible movie. Others seem to have been more impressed with it than I was, so I guess it's up to you!
