I will focus on superheros for my first post, maybe I'll do a second one later (probable, I have time).
Heroes we've seen:Shane Black's Ultimate Spider-ManBlack is the only writer/director I can think of that can fit the quirky witty verbosity of Spider-Man, its heart and its PG nature. The time hasn't come yet for Tarantino's Peter Parker is what I am saying. Ultimate is my favourite run of SM and that's in part because of how well integrated it is in the larger Ultimate Universe, so this could actually happen yet. No X-Men though.
Spike Lee's Luke CageI don't even think I need to explain this one. The Netflix series is uneven, at best. Lee would likely do a better job of making a movie about issues, and he would do it with a bang. Cage is the best black character I can think of for that.
Joss Whedon's X-MenYou need to set up a team of lovable but flawed heroes, possibly teenagers, who have to take on problems larger than themselves ; who do you call? Joss Whedon of course. Scrap the entire current X-Men franchise, it's terrible and keeps getting worse. I want Joss Whedon to give me the X-Men team we deserve. And forget that teenagers thing, I want Jessica Chastain to play Jean Grey. I say start with a mutant registration act in movie 1, with Erik breaking away from Charles by the end and the beginning of the Sentinel program ; Dark Phoenix in movie 2 with hatred towards mutants at its worse by the end ; the Sentinels get shut down in movie 3 and other things happen
(okay that one is a bit of a cheat, he already wrote some of the comics, but how cool would it be?)
The Wachowskis' Mystique (or some other shape shifter)
I mean, who better? Bring in a load of other X-Men characters, make it an R rated movie with lots of violence, add some tech, overthrow a corrupt superstructure. What's not to like?
Alex Garland's UltronEx-Machina, but with lasers.
Heroes we haven't seen:Tarantino's Thunderbolts Marvel's answer to Suicide Squad (or is it the other way around?). The comics are rarely very good but there are some runs and rosters that are worthy of an adaptation. As far as I am concerned, make it an R rated movie and let the baddies go full evil. Alternative director:
Paul Verhoeven, saying something about the fascistic nature of the state and the prison system.
