I, personally, loved this film. Its sweet and awkward, and it warmed my heart. Like i say though, its hard to put a finger on, but you have to have a certain sense of Humor to really appreciate it. If it were a series it'd be along the lines of flight of the conchords/ The office. Theres no goofy, slap-dash 'running into lampost' moments, they leave it up to you to do the laughing, and i personally laughed a lot.
If you liked Napoleon Dymnamite, youll like this, If you enjoy Flight of the conchords, you'll enjoy this, If you Love quaint, cute and Maladjusted comdey, youll love this.
