Le dernier patient

This little gem made me feel stupid, which is a good thing.

What starts off as a by-the-numbers thriller about a killer who visits a shrink to get some kind of closure, turns into something completely different by the end with a plot twist I didn't see coming, although there were several hints given throughout the first hour.

I am not going to spoil things here, but the build-up is just spot on. Cleverly written. We need more movies likes this.
