They made a lot of stupid decisions like killing off Carl in a stupid but realistic way, killing off Merle wayyyyy WAYYYYYY too early.
Killing off Jesus, who realistically should've outlived the group.
I don't really see a need to care about anyone except Daryl anymore.
I hate Negan and I always will, even if he sacrificed himself for the group and saved everyone's lives by doing so it still wouldn't redeem him in my eyes.
Rick, Carl, Merle, and Glenn are probably the characters I was interested in the most, but Rick became less interesting over time, Merle was ****ing awesome and easily my favorite character besides Glenn in the show.
Glenn started off kinda dumb and wimpy, but turned into a bad-ass over time.
Also, does anyone else find Daryl and by the time he left, Rick, really annoying? I hated Daryl initially and hated Rick even more later on.
The shows whole tone becomes too bleak, and yeah I get it but the show used to have charm with all these quirky characters, but now everything's always so dark, brooding, and annoying. We need more fun like the show used to have.
Overall, great first couple of seasons, besides the 4 mentioned above I did form a small attachment to the character "Noah".
If you ask me, TWD Video Game, in 1 single season had more character development then a lot of the characters from the main series.
