Justice League: 10 Ways Joss Whedon Could Change It

7. Better Pacing

One of the biggest criticisms of the DC Extended Universe to date has been the poor pacing of the movies (except for Wonder Woman), and though Joss Whedon will have only a limited role overseeing post-production, his generally tighter approach to editing will hopefully have a significant impact on the end product.

Whedon won't have much say on the style that Snyder has already nailed down, but an alternate approach in the edit room can certainly result in a distinctly different film, and given Whedon's track record, he'll probably ensure Justice League clips along more smoothly than Man of Steel and Batman v Superman did.

That's not to say Whedon will be able to make it clock in at under 140 minutes, but at least it shouldn't feel about four hours long.
