Just posted this on The AV Club, and I imagine it mostly sums up how I feel thus far after two episodes:
So far found the first couple of episodes to be pretty good, but it also seems like it's trying way too hard to be 'the next big drama' without really doing much of interest on its own. I think we can agree, regardless of what one thinks of the shows, that (in no qualitative order) Mad Men, Homeland, and Breaking Bad are at the top of the pile and then there's everything else. Sure there are the Justifieds, Game of Thrones, etcs of the world that come close, but those are the big three.
So take the period piece aspects of Mad Men, toss in the gripping anti-hero of Breaking Bad, and the internal national terrorist tensions of Homeland (plus the opening credit sequence because why not), add in a score that is way too obtrusive, and hope the rest takes care of itself.
I'm going to keep watching for the foreseeable future (at least until the end of the season, I would imagine), but despite some good scenes here and there it's tough to shake how redundant most of this feels.
EDIT: Could also just be that it's tough to get invested in people attempting to attack the US, but that's idiotic patriotism talking I guess. USA all the way! I'm also wondering how long it is until one of them defects because this is TV after all.
