Regardless what happens, one thing I hope they don't do is trivialize all this Negan/Saviors stuff in the next season. They spent like what 1-1.5 entire seasons hyping Terminus, left it on a great cliffhanger, introduced a very compelling villain in Gareth at the start of the next season, then resolved Terminus in like one episode, and concluded Gareth after like 3 or 4. Was very disappointed at that.
We've now spent half a season building to Negan (and with limited knowledge of the comics the hype of Negan from the comic fans has ALWAYS been high) so I sure hope it can deliver a good solid plot arc next season that lasts more than the premiere and a follow up episode.
Looking back on this season I feel like the show needs something to anchor it a bit more, and it's been the lack of a true villain that has held it back imo. The wolves, the saviors, zombies, these are lately all just fodder for chaos and conflict and are mostly interchangeable in my mind (especially since I know exactly zero names as they are almost all immediately dealt with in any given incident).
I think we need a longer lasting Governor/Gareth/Negan type character to really focus a plot line and bring some storytelling to the antagonists. Otherwise its just an endless revolving door of 'oh we're being attacked by _________ today".
