Not sure what this show is trying to accomplish. At first I thought it was a link between the MCU and television. But then all the avenger references were really getting annoying and sort of stifled the growth of the show. I stopped watching after a few episodes. I've been keeping up with it through websites and it seems to me that the show still hasn't found much traction.
One thing I will say is if they want AOS to be a link to the MCU, then S.H.I.E.L.D. needs to be more of a presence in the MCU. With Virtually no presence in IM3 and none inTDW, SHIELD hasn't loomed largely in the MCU since the avengers. I was really hoping during the break they would seriously retool the show and aim to link it to CAWS. Strong SHIELD presence in that movie, which could make for some very strong television. It's still early, so I'm holding out hope that it can be done.
