Especially liked:
1. Limited deviance from comic storyline
2. Continuation of zombie kill shots that are a clear homage to George Romero (machete in skull, close up)
I didn't really like:
1. The choice to have everyone at gunpoint just to emphasize how very civilized and forgiving Rick's crew can be.
2. Carol. I get that she's popular, and she certainly keeps things... interesting... but she's too much of a powder keg, and the writers keep re-inventing her and her relationship to the others... I'm just sick of her.
3. Having Michonne's sword be used to kill Senator Monroe's husband. That added an unnecessary extra weight to Michonne's inner turmoil over wanting to hang the sword on the mantle vs. keep it on her, ready at all times, making it a more literal and less symbolic quandary, as originally intended.
4. The choice to have Father Gabriel go suicidal/homicidal on everyone -- it's created an unresolvable conflict in the plot. That means they'll either have to ignore it, waste time on resolving it, or kill him off. Either way, it would have been better if Aiden, or whatever his name is, had just left the gate improperly secured (in the end, that's kind of what he did anyway...)
I have mixed feelings on:
1. Making Morgan a martial artist... I feel they did that specifically to put him on more even footing with Michonne
... it feels forced and unnecessary.
2. The Wolves (Scavengers in comic) weird and convoluted "trap"/base of operations (?) thing... they're making a big deal out of these guys, and I don't know if it can deliver without overshadowing future conflicts with
Still, all in all, a good season
