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

It’s not bad or unwatchable but despite the amplitude of the spectacle, the end result is underwhelming.

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.

While it doesn't offer any answers, it both thrills and makes you think.
