I saw the movie without knowing what it was about. Looking at it, the description can be misleading coupled with the trailer which makes it look like there are some sort of thriller/horror elements to it: this is not the case! Better stay away if you're looking for action.
As for the movie itself; The major plot point in the middle only lasts for a short duration and the rest of the story is basically told nonverbally which is great.. if it wasn't for the whole wrap around. The movie fills it's time with long shots and rather pointless dialogue. I'm not the least bit suprised that it is based on a short story. I'm not sure if I would recommend it but it certainly isn't as terrible as some users make it out to be on IMDB & co.
