Minor factual / tactical peeves:
Why does the church still have ELECTRICAL power (for the bell)?
How does a woodchuck skull , intact, fit down a human esophagus?
(Recurring problem) - How do you get spattered all over your face with zombie blood and not be infected?
Why would Andrea still be noisily trying to put the gun together, when she knows how imperative it is she stay quiet, and she knows she has no clue how it goes together?
Where is Tyrese?!
But as I say - these are minor quibbles - the proof is in how we love and care (or hate and wish ill upon) the human characters. I'm wondering if they're gearing up for Shane not being killed, they're making him seem so sympathetic (and Lori such a bitch toward him).
And I think so far at least, Season 2 is in line with my analysis in this awesome essay collection you should run out and get to read as you're watching the series. The whole first episode is occupied with protecting children (at huge risk to the rest of the group), re-establishing marital bonds, and getting rid of Shane as a threat (as non-violently as possible, so far). The only possible exception is that Dale looks like a bit of a pill, whereas in the comics he's heading toward hooking up with Andrea.
The whole church thing was interesting, if a little heavy handed. No one remarked on why zombies were there, worshipping Jesus, and I think that would've been the more interesting part, rather than having a couple of the human characters go in and say (rather predictably) "Why God?!"
