I can understand how this movie may not be for everyone. It's dark and quiet with comedy more in the silence than the dialogue. It has a very personal and secretive tone, and I would recommend watching it alone rather than in a group. Odd, soft-spoken, and questionably allegorical, the best way to enjoy this movie is to connect personally with the characters and try to understand their positions. You don't have to want to cut off your arms to understand John, you just have to know what it's like to want something desperately, feel outcast and misunderstood, or to be so comfortable in your own security that it makes you want to break free. It shows, from both sides, lies we tell ourselves and others in order to fit in. This movie is tragic in its humanity, hilarious in its tragedy, and ultimately true. Good actors, interesting plot, and it gives viewers something to think about. It's definitely worth watching on the off chance it will be for you.
