I don't know about you guys, but I'm getting pretty excited for the July 18 release of The Purge: Anarchy. The first film was either one that you loved or hated, and I have a feeling that the second one will be exactly the same. More on the action/thriller side of things, [The Purge: Anarchy](movie:995841) explores a much wider area, and has many more characters and plot points than the original ever did.
From the four clips that have been released, it looks to me like there are going to be five main characters, who all have to work together to survive the night. A husband and wife, who's car breaks down just at the commencement of the annual purge, a young girl and her mother who are kidnapped from their home, and then of course the guy who's out purging for revenge, but ends up saving the other four who have found themselves in a heap of trouble.
