20. Zack Snyder

Whenever a studio ecutive needs a reboot of something and his sole creative direction is "Make it grittier!" Snyder is the dude they call. He'll totally bro up your Superman by sucking all the joy out of every frame and adding muscles. Big, ripply, 300-style muscles. Oh, did you want Superman to be a shining light of morality in a harsh and cruel world? Screw that candy-ass shit. Superbro is gonna crush some buildings and give zero fucks about collateral damage. Grittiness: unlocked.

_Zack Snyder's signature recipe: Take one happy-go-lucky superhero, blast him with a fire hose of muck, then order him to brood or he gets the Kryptonite. _
