A single, overwhelming problem.

Rating: 4/10 (15 December 2010)

CAVEAT: HERE THERE BE SPOILERS. Mild ones. The functional failure here was the pattern of giving facts and taking them away, then ending by giving us a fact that isn't taken away. As a device to show a character is losing her mind, this technique has one large pitfall: seeing the finale through her eyes rather than those of a trusted observer. We don't know if we can trust what we've seen. The movie creates a pattern of physical wounds, personality conflicts, violence and death occurring, then being nullified -- not being healed or overcome, but going away ab initio, every single time. When the last act ends with another death, who's to say the victim won't pop up and be fine? After all, that's what happened every other time during the movie. Why shouldn't this death be reversed as well?
The actors did a great job, and the tech was excellent except for sound quality (but they may have had location problems; no big deal.) My complaint is strictly with the writer, or whoever owns that ending.
