Ava DuVernay
I'd like to see Mangold back, Logan is the best super hero film I've ever seen and I'd like to see what he could do with a team. I may be shooting myself in the foot though because the 3 films I've seen of his are definitely small cast based.
I'd like Vaughn back as well he did great with first class.
The Russo brothers have made my favorite MCU films so I would be very happy to see them take a shot at the X-Men.
I think Ava suits DC more, especially as she has said her fave superhero is Big Barda.
Jordan Peele would be my pick.
Christopher Nolan for the first and maybe second then Joss Whedon. Him and Snyder’s visuals look like they pulled them straight off the books.
Obvious answer is
Bryan Singer
I kid...I kid. But if I am being honest - I'd like to see Ta'Nehisi Coates as co-writer/co-director along with Jordan Peele. They can bring in Gareth Evans as the action consult to maximize the action bits
I liked the Singer movies a lot actually, but I'm ready for someone else to give it a shot.
The best answer: James Cameron
