It’s been eight years since the release of Zach Snyder’s beefcake epic 300 put movie buffs on notice that the future of action cinematography was endless slow-motion, excruciating speed ramping, and ever more phony-baloney green-screen tableaux. That might not seem like a long time, but in Hollywood terms it’s a freaking eon. It only took two more years than that before Sony kicked Sam Raimi to the curb and rebooted the Spider-Man series entirely with a younger, cuter director. So maybe Zack Snyder is lucky Warner Bros. greenlighted a straightforward sequel to 300 rather than handing a remake to Fede Alvarez or somebody.
