I just watched Gnarr, very enjoyable. I tend to watch a lot of documentaries on the streaming site. I loved The new Ross McElwee as well, if you like personal documentaries he is one of the best. Start with Sherman's March. The next thing I plan to watch is general orders no. 9, which was recommended on the PFR blog.
I'm also slowly working my way through the Wallander episodes, which have all been amazing. If you like thriller mysteries with a bit of darkness to them this is the one.
