What I've found weird is the PQ seems really good on many of their originals. The Marvel shows, Narco's, House of Cards, and Stranger Things look great. However when I go to watch a movie or another TV show the PQ often seems subpar. I've wondered if they give extra bandwidth to those shows. The only Netflix Original I've watch that I thought had less than steller PQ was the OA.
That being said I pretty much only watch originals on Netflix. If there's nothing to watch I let it lapse until there is.
