Good start, but then it gets ruined

It isn't all that great, actually. Really cheesy and very predicable of how certain scenes are gonna turn play out. However, I guess that's the charm of it all, because I would consider this one of my guilty pleasures.

This is a must-see and one of the best documentaries - and films - of this year.

I think this is a new genre that they're all sort of working their way through it and haven't got all the kinks worked out yet but it's a genre that works for me.
