A lot of fun.

It's funny, it's tense, it features two great performances from two actors and the director expertly creates a web of odd tension where you actually don't know what is happening for the majority of the run time.

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

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