Some things I liked some I did not.

It was OK. I don't see why everyone loves it so much. It wasn't very smart or deep or well-directed.

if their story seems completely bonkers, almost like a feverish work of fiction, you ain't heard nothing yet.

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.
