The Vampire Diaries--Season Six
I used to be the biggest fan ever of TVD. I watched religiously every week. I wrote fanfiction. Seriously I really loved this show. Then something weird happened. I got irritated with the storylines. First I was never for the whole Stefan/Elena thing. I just didn't find them compatible and the showrunners were like "STELENA FOREVER!" So I pulled back and started reading recaps and watching select episodes. I basically watched Seasons 1-4 pretty regularly with gaps periodically. I dropped it season 5 and 6 other than recaps. My intention is to go back and watch the show eventually (especially once it ends). Personally I think I just don't trust the showrunners and want to see how they handle it before I get invested it again.
BTW they actually did a few things I liked in recent years like Delena, Alaric being back, playing with Steroline, etc. So it is definitely on my to-watch list.
I was also a huge fan of Revenge in season one and two. I watched pretty regularly although a few storylines turned me away. First I was never a Fauxmanda fan until she was gone. I was also so bummed by the "INITIATIVE" storyline of season two. Then season three saw some crazy shenanigans with murder, the Graysons, and other things. Season Four has been pretty great and I tend to watch select episodes after reading the recaps. I just can't muster up enough interest week to week.
Like TVD I expect I'll watch the whole show once it is over and I see how they ended it.
I was one of the biggest Gleeks in season one and then it just sort of lost it's luster (?). Honestly I was totally on board for the first 13 episodes of season 1 and then it just went downhill for me. I stopped caring about the characters. I felt the weird quirks of the characters stopped being charming and became ridiculous. Then they moved the show to New York and it was a little too much. I'm still following it to see how it ends but I could care less week to week.
