    I was prepared to not 'get it'

    Another poster nailed it. The last screens explained it all quite tidily. Only thing I don't understand... the folks that didn't understand lol Excellent film and I'm glad I watched it.

    The makings of a cult classic, but a failed ending

    The acting was OK and the directing was good. The mood of the film was exactly what I think it should have been and the tension keeps increasing as the movie goes, so it was captivating. All in waiting for the end that will explain it all. Alas, it kind of went the way of Phantasm, where you don't know where reality begins and fantasy ends, thus invalidating most of the qualities of the production.

    I liked the main character. A gorgeous redhead who doesn't act all passionate and crazy, but coolly tries to figure out a situation that would have made most people crack. The other characters were kind of secondary, but they did their job in a story that is about what's going on in the lead's head. Perhaps I wasn't in the mood for mind bending movies, but I also generally hate films that end with "oh, it was all in their head" or "they were all dead" (yes, not a fan of Jacob's Ladder), so I didn't enjoy the ending at all.

    Bottom line: with so many good things in this film - including Izabella Scorupco who is still hot as hell and Ahna O'Reilly moving around in white underwear - I really wanted to like and understand the film and I just couldn't. Too bad.

    Decent mind bender

    Sleepwalker certainly makes an attempt to be a mind bending thriller, and does so with mixed results. The viewer might have to watch the film twice to get the gist of its meaning. I did!

    A woman is found sleepwalking in the middle of the night and has no idea where she is. The police find her and return her to her dorm. She has a history of sleep walking and is concerned it is starting again. After another nights restlessness, she decides to go to the College sleep study program to be monitored.

    After the first time she does this things start to become strange. Things around her start to change subtly. The Dr. In charge takes a personal interest in her case and attempts to help her as things progressively get stranger and stranger as the studies continue.

    The rest of the film is an exercise in uncertainty, nightmares, and amnesia. The film, I thought, was somewhat thought provoking but misses the mark as a real mind bending thriller. It is more a film about a woman with a sleep disorder which turns into a mix of confusion, hallucinations And scattered reality.

    I would say it worth a viewing but don't expect much in way of a strong thriller....

    Bizarre

    Acting was great, considering the script and story was absolute bobbins. I didn't get it at all, I followed it all the way through but didn't get the point of the story. None of it made sense.

    I honestly couldn't grasp it

    For the most part this was a solid thriller. I rank the acting at an 8, and the script at a 4. It was a very mystifying story that I failed to understand, but I still was entertained. The pacing and cinematography were on point.

    I recommend this film to a degree, although I think it takes a special analysis to fully unpack some of the themes. I imagine re-examining some the dialogue about identity would help me sort out the confusion.

    Just take it for what it is- you'll be on a 90 minute mind-bending roller coaster ride. Try not to think too hard about the film's meaning and you will have a pleasant experience.
