I realize, I'm not the typical customer (I think autoplaying the next episode was the last feature Netflix introduced that didn't annoy me and made me think about canceling), but for me the only thing that matters when watching TV in the evening is if it's the penultimate episode (because those tend to end with cliffhangers and I'll want to watch the final one as well) and how tired I am/how late it is.

All autoplay does for me is saving me the click on next which I'd click 100% of those times when I don't close Netflix right at the end of the old or start of the next episode.

I can't even understand how it would make people watch more (unless they barely watch and just didn't realize a new one started)
