I'll say one positive thing and then leave you be.
The writing and characters were extremely believable. Its main strength is that its dialogue and story felt real, or at least real for its own quirky universe. It was never abruptly interrupted by standard movie story cues. It threw out the formula.
It felt more like I was peering into a different reality than watching a movie.
That was also it's weakness. Most people want the "movie" ending. Most people want it to be more clean cut.
