I have watched two interesting but quite depressing Arnie films recently that I would recommend.
Maggie (2015) - this is set in a post-pandemic world where infected people turn into zombies over the course of a few weeks. The plot centres around Arnie protecting his infected daughter as she starts to turn. It was light on action and heavy on mood, and certainly a different take on zombie films altogether.
Aftermath (2017) - based on a true story of a mid air collision between two planes, leading to hundreds of deaths. It is told from two perspectives - number 1 is Arnie who loses his family in the crash, and number 2 is the air traffic controller who caused it. I found it interesting how they played out the logicstics of something like this happening, although the last 20 minutes of the film did take a bit of an odd turn. I read after that this film was made direct to video so never got a cinema release - quite strange for a Schwarzenegger film I thought. Glad I watched both though
6 out of 10 for each film
