Stylish but barely mediocre overall

This is a small, humorous movie in some ways, but it has a huge heart. What a nice experience.

It’s sentimental, ridiculously long and only occasionally funny

If you're interested in the topic at hand, you should just watch it and judge yourself because the reviews have gone very biased by people that didn't even watch it and just hate (or love) the creator. I liked it, it was well written, narrated, and directed and it was about a topic that interests me.
