This is where streaming without commercials wins big. In the space of a typical two hour movie you can watch:
* 2 episodes of an HBO/Netflix type show where "hour long episodes" are actually an hour
* 3 episodes of a TV show where "hour long episodes" are 40 minutes
* 6 episodes of a sitcom type TV show where episodes are 20 minutes
With series, it's much easier to try it out and decide if you like it. Then, when you find something you do like, there's more content for the viewer to enjoy plus the possibility for storytelling and character depth that movies simply can't match in 2-3 hours.
