I´ve been a fan of the show for a while but Negan also irritated me just as he did to you. Yes, when he came in the series it was amazing. The way he acted turned The Walking Dead into some kind of SAW series, which was cool. But it never got as fun and exciting as the first episodes. Once they stopped being afraid of zombies (which i can understand after a long while of surviving), it wasn't really The Walking Dead anymore.
