I tend to drop very few shows entirely - though I have known to take longer breaks from them from time to time because, more often than not, I tend to think that I'm not in the mood for what a certain show has to offer, rather than the show being bad enough to drop.

At the same time, I stopped actively following the new stuff on all the streaming services I have and tend to watch new things filtered by recommendations from fandom and/or reviews and "best of [Year] lists". To save money, I've also now gone back to consciously rewatching and fannishly working with older shows (Criminal Minds being the current case in point *heh*). I noticed a while back that the flood of stuff available through streaming was turning me into a more passive consumer, and I didn't like that, so I'm trying to paddle against that stream a little.
