I guess I'm in the minority in liking last night's episode a lot more than the previous two. Lots more action and we are finally getting a lit bit of what's going on with everyone instead of these character-specific episodes. I'm liking that Carl made it to Negan's HQ - I figured they were going to use Daryl instead, so it was cool to see this come to life. Yeah, Carl probably should have shot Negan, but where's the fun in that? And keep in mind, he's a scared kid with one eye.
As for overthrowing Negan, I don't think it's all that simple and that's what I think they're trying to portray. So far, we know he gives you an iron to the face for minor infractions/fun, beats people's head's in as an introduction, and is willing to kill off every man in a community that acts up. His enforcers have it pretty good (despite random abuse/scares to keep them in line), so they're probably not looking to overthrow him. I think he's got most of the saviors sold on his dictatorship being better off than people being on their own as well.
As for communities rising up against him, I think that was the point of the previous episode where they let us know that all the men were slaughtered. They've demonstrated a few times now that if you are the person committing the infraction, it might be someone else who receives the punishment. If you're Rick with a girlfriend, a teenage son, and an infant daughter, it'd be pretty scary to think about what he could do to any/all of them if you tried, but failed to take him out, or what his successor might do even if you got to him. If you care about anyone in your community other than yourself, it would be tough to do much against him knowing the consequences.
Agree with everyone else on getting rid of Spencer. I hate that Self-entitled whiner.
Rosita and the one bullet thing is beyond stupid. Way too much storyline about it at this point. That single shot better have a big payout for us in the near future.
There was another clip of paralyzed-with-fear Rick in next week's preview, so I think you're right with him holding onto Judith for a while. It's not like he doesn't have half a dozen wives sitting around to help take care of her.
I think the build up to the mid-season finale is going to be a fun ride.
