There's a lack of lines in the show that makes it disingenuous to compare to Madmen, Breaking Bad. Especially with Mad Men you get to play with that whole Mod sense of 60s visual style. Walking Dead's cinematography is actually quite well done, in my opinion, it can tell a lot in the haphazard mess. The scene of sheriff whatshisface (I've fogotten most of the story) driving up and walking through the dead and abandoned gas station is wonderfully well done, and gives a good sense of isolation. The rest is good to great on a visual scale, ridiculous CGI explosion at the end notwithstanding.
