I don't know how excited I am for it. I like the show, but it started going down hill after the pickle Rick episode. They got a little better throughout season 3, but Idk. Also the fan base is actually killing my enjoyment of the show. I know they shouldn't, but they make it really hard.
Personally I don't see it as a progressive series - like I can watch a random season 3 episode without watching any of the build-up episodes.
