I'm afraid that this behaviour in general, not just related to Netflix, is doing the industry much harm.

My own experience is that recently I just don't want to get into new shows, at all. The story goes - I start to watch a show, I grow to like it, get all emotionally invested, the show gets cancelled halfway and I'm left out in the cold, dick in my hand, no satisfying end to a story arc, nothing. Most recent example is Counterpart which was (imo) phenomenal but got the axe after two seasons.

I'm not expecting the shows to run in perpetuity, just for them to run their course, tell their story. Great shows aren't great because they last a long time.
