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.

This story discusses major plot developments, including the ending, in “Superman,” currently playing in theaters. In the climax of “Superman” — the first feature film under the DC Studios banner, and the official big screen launch of the new DC Universe — the city of Metropolis is split in two.

"Superman" puts a cool twist on the Man of Steel mythos. James Gunn's DCU movie includes post-credits scenes and a teasing cameo. Plot spoilers ahead!
