Other movies I rented:
The Grey - eh, it was okay. The obviously-CG wolves really made it difficult to feel any sort of danger or tension at the survivors' plight. In fact, some of the attacks took on an unintentionally comical tone. I don't want to give anything away about the ending; however, even though the ending might be considered realistic, it just leaves you wondering "what was the point of all that, then?"
The Road - this one was recommended to me by a friend at work and it was pretty good. The performances were really good for the most part and there were a few truly nightmarish scenarios. Again, the ending left me with the nagging feeling of "what was the point?" So, two really depressing movies in a row did not make for a very fun movie night.
