Query: This had an effect, but not a good one.

I heard nothing but good words before I saw this. I didn't hear or read any criticism, so I went into the movie with an open mind and lots of hope that this would be a movie that I would enjoy. I was very wrong. I was disturbed by parts (and I've seen some very disturbing movies, but this was just too much for me) and I was also bored halfway through the film. I saw about half and didn't watch the other half. I also couldn't stand all the switching screens all the time, I was losing my train of thought as to what was actually happening. I love 'psychological thrillers' as I would call this movie, but this..this was just not what I expected. At all. It almost makes me wonder if everyone was watching the same movie as I was. But I guess they were. Maybe you'll have to see it for yourself, but for me, I'll pass.
