Star Trek Voyager. I hated the show but for some reason I just had to see it, there was a small part of me who thought it will get better, just like TNG or DS9 - both of them started very weak but got better, but then it suddenly stopped.
Star Wars Rebels. The first season was OK, nothing special but enjoyable. Unfortunately I have also watched season 2, not sure why, there were maybe 2 episodes I liked. I don’t even like the opening 2-parter and the closing 2-parter which most of the people claim are good. And the sad thing is that I’ll probably even watch season 3 😦
Game of Thrones. The last season I truly liked was the first one. I don’t even know if I should start watching season 6, all the characters I liked are dead.
