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

True to its essence, the characters remain on the same line and manage to entertain the viewer, each highlighting their own distinctive qualities or touches.

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.

There's a more than satisfactory amount of boom-boom in the movie's trim running time.
