James Gunn's Superman movie swooped into theaters Friday, offering thrilling battles, big-hearted heroes and an amusingly untrained canine sidekick. You might want to see the superhero epic if you're into other films written and directed by Gunn (such as Suicide Squad and Guardians of the Galaxy) or want to catch the cinematic start to the new DC Universe.

Superman is off to a great start at the box office. James Gunn kicked off his reboot of the DC Universe with the second best opening of his career, and the best ever for a solo Superman movie.
