Joss Whedon has incurred the wrath of some fans of the DC Extended Universe by liking a tweet that criticized Justice League villain Steppenwolf.

The reviews for Zack Snyder's film have been been mixed -- it hovers at 43 percent on Rotten Tomatoes -- with several counting the villain's motivations and CGI depiction among its flaws. Vanity Fair writer Joanna Robinson echoed those sentiments in a tweet, comparing Steppenwolf to the Dark Elf Malekith from Marvel's Thor: The Dark World: "#JusticeLeague’s Steppenwolf is the worst comic book movie villain of all time and not even Malekith the Accursed comes close." When DCEU devotees saw Whedon "liked" that critique, some turned on the director for what they viewed as a betrayal.

"You are absolutely repulsive," responded one fan. "How dare you even like this tweet?"

"Your fingerprints are all over this film & you had yet to voice out any kind of support for it," another wrote. "You are despicable & you have singlehandedly ruined Zack Snyder's Justice League."

It's been suggested by producer Charles Roven that Whendon actually shot 15 percent to 20 percent of the movie after Snyder stepped aside in the wake of a family tragedy. Early assessments of Justice League range from fun to boring to chaotic, with some reviews highlighting a disconnect between the styles of Snyder and Whedon.

Justice League's Rotten Tomatoes score was revealed overnight to be 43 percent, far lower than Wonder Woman (92 percent), but ahead of Batman v Superman: Dawn of Justice (27 percent) and Suicide Squad (26 percent). However, the film is on track for a $325 million worldwide opening.

Opening Friday nationwide, Justice League stars Ben Affleck as Batman, Gal Gadot as Wonder Woman, Henry Cavill as Superman, Amy Adams as Lois Lane, Jason Momoa as Aquaman, Ezra Miller as The Flash, Ray Fisher as Cyborg, Jeremy Irons as Alfred Pennyworth, Diane Lane as Martha Kent, Willem Dafoe as Nuidis Vulko, Ciarán Hinds as Steppenwolf, Jesse Eisenberg as Lex Luthor and J.K. Simmons as Commissioner Gordon.
