As I said in the general MCU thread, I liked that Mac was picking up guns like he was playing a computer game this week.
I like the twist with Mace, in as much as they're really using him as a slight variation on his comics incarnation. Not sure if I like Coulson calling the shots behind the scenes, he didn't seem to enjoy being Director last year, so hopefully he'll start to feel the burden of responsibility and not just call the shots and forget about the rest.
And I keep forgetting that Melinda Maybot doesn't remember she's an LMD, so that look at the end was more a WTF than a "shit, rumbled"
Also, Luke Cage reference with the sniper using Judas bullets!
