I don't know about the director, but I *loved* the version of the team that showed up during the Thanos Imperative. Specifically Star-Lord, who is essentially nothing more than a normal human who is facing cosmic level threats with nothing more than a cool looking helmet.
I was also a big fan of the version on Earth's Mightiest Heroes.
JD and Eliot will be gone in a few weeks, they're only signed on for six episodes to transition the show into the new format. Carla is not signed up at all, and will likely appear, if ever, only as a sporadic guest star.
