The Revenant
A big thank you to ChronoGrl for recommending this. I really liked it.
It was funny without overloading the humor and without being stupid. It was surprisingly dark at all the right places and the story kept evolving so that it never got boring or predictable. It started to lose focus around the vigilante gunslinger part but it explored a realistic scenario that people might experience if given the chance to be immortal and it gave way to the awesome last part of the movie. I loved the ending. So depressing and sad and the very last sequence was excellent.
I recommend this.
