Re: Who deserves the most credit for MCU: Phase One success?
I think it's Kevin Feige, no contest, simply based on coming up with and following through with the entire concept of the MCU. Without Feige and his vision/foresight, we never get RDJ as Iron Man let alone anyone else from the MCU. And even if they did, I don't think anyone other than Feige could have executed it, regardless of how many talented people are at MS.
