I don't like them that much but they seem to be doing well overall. I don't think Marvel's too upset about how they've turned out.

Agents of SHIELD was a misfire at the start with the weird Coulson mystery, two leads that didn't seem all that important or interesting, and they were basically treading water until Winter Soldier blew up SHIELD. It just lacked focus at the start and lost a lot of people (including myself.)

Agent Carter was well-liked but didn't get the ratings. I thought it was OK.
