Brooklyn 99 was my junk food show, just put it on and turn my brain off after an exhausting day. Was getting fatigued with it by season five, and I think that should have been the finale because it ended with most of the character arcs wrapped up, but then they decided to get it uncancelled and that sixth season was a piece of shit. They really fucked Amy over trying to make her the new Gina (Who I was glad they got rid of, she just shits me) and having a whole episode being a lecture on sexism and harassment played straight with no jokes?
I had this exact same experience with the show. My friend showed me the first few episodes a while back, and I didn't really get into it, but I started watching it again during the lockdown because I wanted something to watch while playing
Animal Crossing.
I was really into it for the first four seasons, but then it started getting really preachy and obnoxious. I'm not one to constantly complain about "muh SJW themes" every time a black person farts onscreen, but it felt like they were trying way too hard, and episodes would be brought to a screeching halt so a character could rant about sexism or the issues trans people face in prison.
I originally thought this was the fault of the writers, but apparently it was Andy Samberg who was pushing this crap, which is very disappointing to learn. Anyway, stopped watching midway through the fifth season and I doubt I'll start again.
Turning to other shows I fell out with, the reimagined
Battlestar Galactica was my favourite thing ever for the first two and a half seasons, but then midway through Season 3 it disappeared up its own arse and never re-emerged. It was very sad to see, but I still re-watch the first two seasons from time to time because they were that good.
I mentioned this in another thread, but
Cuckoo with Greg Davies had turned into an absolute dumpster fire by the fifth series. I still have no idea why they kept it going after Series 4, which ended things perfectly.
Sherlock's quality noticeably dipped in Series 3, and Series 4 was a complete trainwreck. I've heard it's not officially over yet and there could be a fifth series. I hope that never happens. The show well and truly ran its course.
The Timeless Child shitstorm is well documented over in the
Doctor Who thread so I won't go over it again, but to be honest, the revived series lost its way at Series 6 and I've only been watching out of loyalty ever since. I may stop doing even that given recent events.
Loads of people mentioned
The Walking Dead, and I'll add my voice to the chorus. I stuck with it until Season 7, but it had been boring rubbish since Season 5. I don't understand how anyone watches it these days. There was one episode which lasted an hour and it was literally just Rick and Michone walking around an abandoned funfair.
