Lack of good storyline.

The plot isn't so bad, but the pace of storytelling is too slow which makes people bored. Certain moments are so obvious and unnecessary for the main plot. I would've fast-forwarded those moments if it was an online streaming. The ending looks like implying a sequel, not sure if this movie will get one

It is an exhilarating, distressing, funny and profound film, with one of the more memorable film scores in years,

It really made me laugh, but for some moments I was tearing up because I could relate so much.
