I found Season 6 very frustrating and disjointed as a whole. 6a's biggest flaw was having the story centered around two days, imo. Plot stagnated and character development suffered b/c of that, imo. Gimple clearly has trouble balancing the large cast of characters screen time, where he has to resort to separating certain characters and relegate some with bottle episodes.
Also the quarry walker herd invasion dragged and took up too many episodes than it needed to, imo. Heck they milked it for 9 episodes. It also overshadowed the whole Wolves arc, which ended up being a let down after all that hype in 5b, imo.
Not to mention the whole dumpster fake out took away from the story and was nothing but a gimmick in the end.
6b was an improvement over 6a but I still had some problems with it. The 2 month time jump undermined some of the loose ends from 6a. Walker Deanna lurking around the woods for two months
, even though it was implied she died being overrun and devoured by a bunch of walkers, was one of the most absurd moments of 6b (maybe even season).
Certain characters making asinine decisions/choices so they can end up being in the lineup for Lucille became contrived. A forced death of a minor character that didn't serve much purpose but shock value, imo. I'm also not a fan of most of the romance between certain characters this season, which again felt very forced and unnatural, imo. I don't want this show turning into a soap opera.
Some characters both old (Carl, Sasha, Rosita, Aaron) and new (Heath) were very underdeveloped. Aside from "First Time Again" and "Here's Not Here" I felt they wasted Morgan's character for most of Season 6. Him sparing the Wolf ended up being meaningless and had little to no circumstance to the story after it was somewhat resolved, imo. I still like the character but aside from his backstory episode with Eastman I feel the writers didn't really know what to do with Morgan, which is a shame b/c Lennie James is one of the best actors on the show, imo.
I wasn't digging how for the most part the Saviors came off less intimidating as Rick and co. took 'em out almost effortlessly until 614 and 615. "Your hero is only as good as your villain." Throughout the series Rick's survived through some of the worst circumstances and dilemmas imaginable, but his cockyness felt contrived and exaggerated a few times in 6b to the point Rick seemed to believe he's invincible.
I know a lot of fans despised the season 6 finale b/c of the cliffhanger, but aside from JDM's impressive performance and monologue, I thought the whole unnecessarily extended 90 minute finale was disappointing.
Season 6 wasn't a bad season but it wasn't great either, imo. Really expected more from Gimple b/c I enjoyed the the previous two seasons very much with him as showrunner. I guess I had my expectations set too high for Season 6, b/c I believed it had the potential to be the best season yet. Hopefully Gimple won't make the same mistakes he made this season with Season 7 but learn from it.
