In general, are you more likely to suggest a complete show or one that ends abruptly with several dangling plot threads?

Stranger Things season 1 would have been a fantastic show if it just ended there (without the final cliffhanger scene). I'd recommend it to everybody. If Stranger Things just ended now, I might still recommend it to everybody, but I'd be decidedly less likely to do so, and it would always come with the caveat "They didn't actually finish it." So not only am I less likely to recommend it, but the caveat means the other person is less likely to watch it based on the recommendation if I do. (I might also say, "Don't bother watching past season X," which is still bad for Netflix.)
