Yeah... it's back, with a new set of boring generic evil bad guys to replace the last set of boring generic evil bad guys.
FIFY.
Honestly when they killed off most of the interesting characters (or the people suddenly disappeared like Maggie did) and basically rebooted the entire show, I just couldn't get into the show anymore.
For me, I think it happened because of all the whining they received for when Negan killed Glenn and Abraham. A lot of people online were crying and whining about it was being too graphic and so scary, so I think that's when the various people controlling the show began planning big changes that killed the enjoyment of watching the show.
My wife still watches it, and began watching the new spin-off/companion series 'The Walking Dead: A World Beyond'. I was in the room for a few of the episodes of that crappy show, and I couldn't believe how bad it was. A bunch of boring, whiny teenagers somehow not dying 5 minutes after they left their sanctuary city.
