John Shaw, president of Theatre Management Associates, described director Patty Jenkins' film "as exciting & entertaining in every way," and praised the characters and effects. "Here's a summer blockbuster as good as Captain America ($370M)," he tweeted.

He also noted how much is at stake for Warner Bros. and its fledgling DC Extended Universe, which has gotten off to a rocky start with "Man of Steel," "Batman v Superman: Dawn of Justice" and "Suicide Squad," which received decidedly mixed reviews.

"What summer film has a lot riding on its success? Wonder Woman. WB and DC comics count on major success," Shaw tweeted. "Thus far, projections are strong."
