Die Liebe der Jeanne Ney
Jeanne is in Russia after the revolution, her boyfriend Andreas is a Bolshevik and the two of them become involved with a baddie who follows them to Paris and threatens the lives of Jeanne and her family. I lost track a little, that's my fault for paying full attention to Pabst's film. It's a complicated story with a distinct touch of melodrama and overacting, something that I didn't expect from so late a silent film. (I probably haven't watched enough of them!)

Imagine a film about a man rescuing his sister from K2, fill it with believable characters who aren't either saints or psychopathic millionaires, make them into mountaineers who do the things real mountaineers would do, use science in the rescue in the way real-life science behaves, make your believable characters act in the way real-life human beings do and leave some surprises in the question of who will survive the rescue attempt. Are you imagining all that? Well this film doesn't have any of those elements apart from the man rescuing his sister from K2.

Los cronocrímenes
A man travels back in time by just an hour, and starts a chain of events that become increasingly complicated. This film explores the idea of the time travel paradox well and kept my interest as the plot became increasingly complex. I got to the end of the film and I had that very satisfying feeling that made me think "I need to watch this again" and didn't mind that idea!
