The Pool: A good thriller that uses everything to it's advantage and builds up tension very well. Granted, it does get a bit forced/convoluted at times. But the story telling does keep you involved in the plot, and there even is time time for a laugh or two.
Cut Off (aka Abgeshnitten): A very enjoyable serial killer flick with Moritz Bleibtrau shining again. It does follow some of the genre tropes, but at least it does not go for every low hanging fruit. Example: the one character you would expect to be in cahoots with the killer turns out not to be.
