Fuck the haters, this show is back on form. Yeah, I don't buy the second phase of Saul's master plan for even a second, but that doesn't make the show as bad as people are claiming. At the end of the day, it's probably still far less outlandish than the back half of season 2, and there's a lot more of a focus on smaller scale spy fstuff (although the final few episodes I expect to be quite action packed).
This show is good again, and I'm not sure I'm convinced by any arguments to the contrary. Even Dana was only used in a scene with Brody this week (which was much needed from a narrative perspective, although also absolutely insane on Carrie's part).
EDIT: Oh yeah, and the bearded Marines are awesome. Here's hoping they don't all die in Iran.
