I was on a search of something to watch and came across Red State. Reviews were mixed, but I had two hours to kill and figured how bad can it be.
Here is the preview: (NSFW, Language)
I actually liked it. It wasn't exactly original, but some of the parallels drawn were kind of interesting. Also mix this without taking itself too seriously, and the movie is pretty entertaining. John Goodman is great, whoever plays the pastor is exceptional.
Picture quality is great considering it seems to be a low budget film (I watched a few minutes of the behind the scenes and looks like they shot on Red One). Editing is okay. Sound quality is actually pretty good too, crank it up.
Verdict: Worth a rental.
