Rewatching first 2 seasons so far because my life is just that exciting. First let me say thats good shit. Couple things I've picked up on the 2nd time around...
When T dog gets cut and gets an infection, Daryl pulls out a bag of Merel's supplies and mentions meth. Its blue.
After Sophia is found. Rick begins to doubt himself. When talking about leading the group on a wild goose chase in search of Sophia, He tells Lori, "I was just out chasing a ghost in the woods. "
I also have a theory about the show being better on Netflix. Obviously aside from the commercials, not having a weeks worth of anticipation in between shows kind of relieves the pressure of advancing the storyline. In other words, I don't seem to be as worried about the pointless conversations/filler. Instead I just enjoy it for what it is, which is a pretty damn good show.
