ok. I'm probably one of the few ATers who doesn't think he knows everything, doesn't agree with everythign he hears from people who read Slashdot, and can actually be objective when reviewing a movie. I actually managed to sit through this entire movie and it wasn't great. But it's not like it's the worst movie of all time, or even close.
First off, the movie is long. It's like they took 3 normal length movies and put them back to back. Let's just say they told too much story. Second, the movie is a slow moving drama. This is one of those movies that has not heard of the concept of action. So for your average ATer, there's too much thought and too much required of an attention span to keep track of it. It was an interesting take on the post-apocolyptic America concept. If you choose to see it, go in to it with an open mind. You may actually like this movie a bit. I highly doubt you'll consider it a landmark movie, but it's better than alot of the crap I've seen people praise.
