If you like the stupid man child archetype then you'll like this film. I personally hate those types of characters. There are some good laughs but the main character and ending were too stupid for me to enjoy.
A kind of 40 year old virgin with a mostly Japanese cast. All the best bits were in the trailer. The hour and a half run time adds nothing but awkwardness. This is an example of a quirky independent flick going too far over the edge.
