More than a Superman (or Batman for that matter) story, Apocalypse is about Supergirl. This modern day origin for Kara Zor-El tells of Kal-El's cousins orientation to the world, trapped between all the various powers that would use her for their own purposes rather than let her be her own person. By the end, she decided to don the familiar \S/ shield and to assume the moniker, Supergirl.
As the title implied, this film was another team up of the World's Finest, Superman and Batman, though in this loose sequel to Public Enemies (based on the comic book sequel Superman / Batman: Supergirl which was a tad bit tighter sequel) Wonder Woman joined in on the action.
A primary antagonist during the movie was Superman's cosmic nemesis, Darkseid. Apparently, no one ever taught him not to tug on Superman's cape. Darkseid's Female Furies made for some intense action sequences allowing Wonder Woman and fellow heroine, Big Barda, to let loose.
I would be remiss to fail to mention the appearance of more intimidating Krypto the Superdog, watchdog of the Fortress of Solitude. Overall, Apocalypse lacks nothing in intense and thrilling action, though for true heartfelt character development or an examination of the Man of Steel one may be better served elsewhere.
