I liked it. It's a little more... artsy... I think that's the word I want... than movies I typically watch but it was good anyway. I really liked the framing devices they used for the different levels of story. It has a story in a story in a story thing going on that's broken up by using different aspect ratios for different levels of the story. There's also some unreliable narrator thrown in there too for good measure.
I honestly didn't know if I would even make it five minutes into this movie but I was engrossed the whole time I was watching it. With my typical kind of movies I would know who to recommend it to and who not too but this one throws me for a loop.
I would say if you get a chance to try this one on the cheap you should give it a shot. In the end, I liked it.
