While it is strange that Marvel would hand off their franchise to a creative mind Like Whedon, who will surely refuse to conform his sensibility and even stranger that he would want to do it after the Wonder Woman disaster and with so many personal projects on the backburner, I have to trust that this will be a good call on both sides. It is no secret that Joss Whedon is my favourite creator, and I'd honestly prefer he stick to his own projects, but they're allowing him to re-write the script, a sign that the control is in his hands. Also, it's safe to assume that Joss is a little tired of the television medium after the cancellation of the daring series, Dollhouse.
So, perhaps this a good move for Whedon, even if the film doesn't reach the standards of his other work, it will surely open doors for him (he has had trouble getting backing for feature film projects since the box office failing of Serenity) so he can finally establish a career as a filmmaker. This increases the odds of seeing the oft-mentioned Goners film project come to fruition as well as a point for the good guys as far as chances of a Serenity sequel go. Considering the positive ramifications, it's hard for a fan of the Whedonverse to be too worried about an Avengers film
I'm not jumping up and cheering quite yet, but I'm all for it.
