Comic book geeks were surprised in May, when it was announced that Zack Snyder would (for family reasons) step away from finishing his work directing DC’s “Justice League,” and Joss Whedon — who directed Marvel’s two “Avengers” movies — was taking over the superhero mash-up.
After seeing the final product, intermittently exciting and sometimes overstuffed, Whedon’s selection makes sense — because Snyder was following the Whedon playbook all along.
Like Whedon’s first “Avengers” movie, Snyder’s “Justice League” falls into three parts: the assembling of the team, the team’s faltering early battles and internal squabbling, and the slam-bang finish in which — spoiler alert — good triumphs over evil.
