It was also just a straight up James Gunn movie with an ensemble cast of misfits. It's like...his thing. That's what's so weird about so many Marvel movies. They gave them to competent directors and basically said "make one of your movies, but with our characters and setting." Iron Man 2 was a Shane Black joint: took place at Christmas, lots of witty banter, there were some buddy cop elements. But the shell of it is an Iron Man movie.
