i must have seen a different film!!

All that we are seeing on the screen is happening with real people, real action sequences in the background, forcing the eye to watch as if we were there.

I think this is a new genre that they're all sort of working their way through it and haven't got all the kinks worked out yet but it's a genre that works for me.

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.
