It's funny watching the elements come together in this complicated scam. On one hand, the set-up isn't quite as complex as it seems, but there's an easy sense of fun in every exchange.

As somebody who had not heard any of this before, it became a curious phenomenon to sit and watch a film and slowly have the realities begin to click into place.

After playing with our expectations, this turns out to be a very different sort of film.

The film's masterful storytelling did its job. The message was clear. No need to overdo.
