Also during this process the showrunners—Joss Whedon's brother Jed and sister-in-law Maurissa Tancharoen—are at the helm of the new series. But the writing is reportedly not up to par. According to Defamer, who is a part of Gawker's online network, Joss needed to be called in to fix a writing issue. Defamer wrote:
"A source close to the show tells us that the latest scripts that have come in have been so bad, Whedon had to pull off a page one rewrite just an hour before the table read. Given that Whedon is supposed to be transitioning full show runner responsibilities to his brother Jed Whedon and sister-in-law Maurissa Tancharoen so that he can focus on his 83 other film projects, this ain't a good sign."
Having Joss come off his writing duties of finishing up the script for the much anticipated Avengers: Age of Ultron is a big deal. Fans should be concerned only if Joss keeps getting phone calls to come in and do some more writing for Agents of SHIELD. This is most likely a one-time thing and it could've happened because Joss needed to come in and help better integrate the show to co-exist with something new that will happen in an upcoming Marvel Cinematic Universe film.
As of right now The Daily SuperHero will label this as a one-time hiccup. Hopefully...
