Honestly, I'm not sure why this was on my NetFlix list. I had spent a couple of months not maintaining it, and when I returned (no pun intended) to see what was next, I saw this. It has Sarah Michelle Geller, so I said, "Eh, why not?"
Unfortunately, by the end, I could answer that question. The why not is the fact that this is one of those movies that tries too hard to be clever. Not clever like Momento, but rather clever like Stay. The whole movie was spent wondering what the hell was going on, rather than wondering why it was happening. Sarah spends the whole movie being stalked by various men and fending them off without knowing why they were attacking in the first place. The effect was to make you feel like she was living someone else's life. But it didn't work.
Finally, at the end of the movie we learn the why. But instead of feeling a sense of "Oh, I get it!" I was left with an "Ummmm..... okay".
The acting was pretty good, and there was at least some resolution at the end, so I won't give it a ranking of Stay, but I do give it a D. Sorry Sarah.
