At first glance it appears that Season 3 is better than Season 2 but once you get into it you see that they simply added a little pointless action to cover up the lame story lines and hugely moronic character decisions.
I get that they're trying to write this huge morality play about good and evil, human nature, blah blah blah, but the problem is that they don't do any of the stories justice as they never flesh them out. We get very little of Andrea and Michonne's relationship. We get very little of life inside the walls of Woodbury. We see almost nothing of the citizens of Woodbury. We aren't given
any rational reason for Andrea's
repeated decision to remain in Woodbury (
after having her friend Michonne tell her it wasn't a good place to stay,
after finding out that Glenn and Maggie had been imprisoned and tortured there,
after witnessing the zombie fights that the people of Woodbury got excited about,
after finding out that Daryl was to be killed,
after finding out that the Governor was a creep, etc.).
The writers
tell us stories, they don't
show us stories. And what little they do show usually amounts to Rick being a buffoon who almost gets everyone killed, this after whining and crying and wringing his hands for a week. Now to be fair, there doesn't always have to be non-stop action, rather, the inter-personal stories can be told, but they should be done in a complete way. We should be given realistic details for the characters so we can understand their motivations -- why are they good?, why are they bad?, etc. Also, we should be shown more details about the setting like the sanctuary town for instance; other than seeing an endless stream of people walking aimlessly up and down the sidewalks that is. The show as a whole is lacking in these important details so when conflicts between characters reach a climax there is no empathy from the viewers (at least not this viewer).
Case in point, when Andrea buys the farm no one really gave a shit. She was such a cardboard "dumb blonde" at that point that she deserved no sympathy.
So, yeah, the only thing you're missing by not watching this show is some laughs.
