I had to watch this movie when I saw how polarized the IMDb reviews were. People either seemed to LOVE or HATE it. I really enjoyed the themes of this movie, the overall message, the acting, and most of the direction. The major problems came for me when the Director got a little too artsy-fartsy, which really only happened towards the end of the movie.
I think the opening scene was brilliant, not only for its candor, but because it will tell you if you will be able to enjoy the movie right then and there. A lot of people will probably turn it off right away, and that's probably for the best. If you don't like it, don't force yourself to watch it, it's a rough and uncomfortable journey.
I give the movie a 6 to say it's above average, worth watching if you're into that kind of movie, but not something anyone MUST see. I look forward to more from this filmmaker, if they can reserve their art school tendencies.
