Very well done movie. Sucked me completely in.

Really liked this, don't agree with the weak ending comment - much happier with it being left hanging than seeing a disappointing conclusion crowbarred in... I thought it was fairly clear what was going on at the end, but there was enough wriggle room left for you to draw a number of different conclusions. Elizabeth Olsen was fantastic. Excited now to see her in Kill Your Darlings, the Oldboy remake and of course the next Avengers. Very talented.

I thought the way the story was told was OK, but the timeline idea was overused. I didn't believe that Martha had lost her social knowledge after just two years. This movie could have been deeper. It could have stepped outside the personal story and made some good social commentary. It did touch on capitalism vs socialism after an hour, but that was a few lines and nothing new. Martha is a misunderstood victim yet all she really needs to do is talk, yet she doesn't because the movie is structured around this very idea. A lot of tension and scenes are based around Martha doing inappropriate things or freaking out and I didn't believe the logic behind it. The formula becomes repetitive and makes the slow pace seem slower. So overall the writing failed to work for me. The acting was good. I'd still recommend this movie because I believe people will enjoy it and not care about what I see as faults.

It's a great movie. Excruciating in so many ways, as it's intended to be. But I'm not a big fan of open endings.

>"We're never really dead or alive; we just exist." What an interesting, terrifying and realistic look into how cults brainwash and affect people. Elizabeth Olsen's performance is great and anyone who is a fan of her should check this film out.
