I watched the first episode of Season 3 and stopped. You know I'm not even sure if I made it all the way to the end of even that episode. Then I read the Tv Tropes page and discovered that they killed off the most interesting character in the next episode, followed by the rest of the main cast over the season - and replaced them with a whole new one.
Going into that Season I wasn't aware that they'd replaced the show runner with the same person who'd left The Walking Dead after running that series into the ground. I'd wondered why Season 2 could end on a high, with the potential for interesting characters - then 3 begins and all of a sudden the writing plummeted (where did all those super competent soldiers at the Mexican border go to? Oh, they've been replaced by these childish idiots who'd be better off in Z Nation. Oh, and now they're all dead. Woo!). Which I suppose is more to do with the politics of AMC manoeuvring employees from the main show onto other projects instead of firing them.
...Not to say that the main show was any better for their loss. For the first few minutes of the new series things seemed to have improved slightly till people started acting stupid again (then we lost Rick Grimes and I was done). Its just a pity that Fear the Walking Dead seemed to be getting better and had the potential to replace its parent series, but both wound up being little better than Si Fi originals. A HBO quality Zombie drama will come along eventually hopefully, though it does seem like a genre best suited for slocky junk.
