(A tangential rant). One thing I've found extremely annoying is when I'm buying the bluray (or dvd) season sets of a current show I like watching a lot, and then the show suddenly turns into garbage and/or I find the show becoming lackluster or outright boring. For example, this happened with The Blacklist for me. I purchased the season 1 and 2 bluray sets, and then season 3 turned to crap. I also found the subsequent seasons somewhat lackluster too. Since then, I haven't bothered purchasing any further bluray season sets of The Blacklist. (The only reason I still watch The Blacklist, is mainly because I'm at home on Friday evenings). A more recent case was Designated Survivor. I liked the 24-style conspiracy plot in season 1, where I purchased the season 1 dvd set. By the time it was season 2, it turned into a completely different show resembling a WestWing-lite or HouseOfCards-lite which was executed in a rather bland boring manner. Since then, I've been very reluctant to purchase any dvd/bluray sets of the first few seasons of any newer shows I've been watching.
