Movies are easier than full series since they only take 2 or 3 hours. Shows with short seasons (like Black Mirror) or ones with only 1 or 2 seasons would work too. A Netflix original content thread isn't a bad idea, or maybe a DRC Movie and TV club type thread. Or both. But it would be hard to coordinate with TV shows. If we did something like, 'watch 2 episodes per week' or something it could work but I know if I got hooked on a show I wouldn't want to stop and then it would be more difficult for everyone to stay on the same track. A movie a week would be much easier.
Think up some movies you would like to see, or see again, and let's give them the Black Mirror treatment.
