It's an amazing and heartbreaking story.

A film of deceptively outspoken contemporary relevance, this is cinema at its most alert, alarming and alive.

The movie's not perfect, but it sticks the landing of its message. It was engaging - thrilling at times - and I personally thought it was a great time.

One of the film's great tricks is that, for a time, you think it will go down a rabbit hole of unrealistic glorification.
