Andrea is again being used for character development purposes, T-Dog #2/Oscar getting killed off and being replaced by Tyrese (seriously wtf man?!
), Michonne finally shows an emotion besides anger (for 10 seconds...),the Dixon brothers being reunited and Andrea staring there like a deer in the headlights (a mix of good and bad IMHO). Other points I really enjoyed:
Axel going pedobear, making a nod to the comic via Axel calling Carol a lesbian, the eye gouging, Rick losing his sh*t and seeing Shane, Carl slowing becoming more of a badass, Michonne realizing Andrea ain't her buddy no more and saying "You NEED me."
Overall it did a decent job as a mid-season finally but I'm certainly not looking at this show with the same glossy eyed enthusiam as I once did.
