Fanciful, disturbing, and wildly original, it announces the arrival of a fresh, bold voice in American cinema.

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.

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

By the time the dramatic fireworks start popping off, each one feels earned.
