I reckon they’re going to repeat the same mistake as the season three finale where they built up to a big fight with the Governor, but then it became a really small skirmish and just another part of the build up to the actual fight in the season afterwards.
I’d be surprised if Negan doesn’t find out about the group’s plan to attack him, and in turn Negan would probably attack first and cause them a major setback. But then again, that’s all the plot can really be can’t it? That or they attack Negan by surprise and he goes off into hiding to regroup. Negan is surely going to be around for another season…
I haven’t read that far in the comics but I do hope they manage to do something more interesting. It’s hard to see where they will wring the drama out of the Rick v Negan stuff, considering it’s just two leaders killing each-others’ followers and the show has done so much of that it’s hard to keep enthusiasm for it all.
