I actually had never heard of this, but it actually sounds pretty neat in a Netflix-y sort of way. I'm not a big fan of Natalie Portman (there's just something about her I don't like, in the same way there's just something about, say, Reese Witherspoon I DO like), but the story looks like my favourite sort of creepy mindtwist.
The review actually raised an interesting point for me. I remember when 300 came out, there were all these jokes about how... uh... Lead Spartan Guy's abs should get their own credit, and it was definitely marketed towards women in a very sexual manner. Hell, I had other women telling me how I should go see it even if I wasn't that into the subject because the male cast was so damn sexy. Why is it okay to suggest that women should want to see a movie because of the meatshow, but if a guy says he wants to go see a film because some hot chick (similarly scantily clad as the men were in 300 or moreso) is in there, holy crap look out, he's a total sexist douchebag? How is this any different from saying you like the graphics in a video game? (Well... I mean, okay, it's sexier, but still.)
I wonder how much of it comes down to insecurity... chicks who don't want to think their significant others might want to watch it because they think they might not measure up, and guys who say they wouldn't want to watch it because they think it's what their women want to hear.
