All I have to say about the choice is
I thought they Marvel would get more experienced directors for their movies. It seems like they're still going too small if I have say anything about it right now.
Alan Taylor for Thor, Russo Brothers for Cap. Getting TV directors to direct movies is what screwed over the Brosnan Bond movies in the 90s, so I'm weary about having tv directors with little big film experience to direct. At least Whedon directed a Sci-Fi movie before The Avengers.
They must have had a damn good pitch and I hope Marvel knows what they're doing.
