Too long and makes no sense.

(Nothing but spoilers)
Batman hates Superman. He really hates Superman. Why? Because people admire Superman, almost deify him, and it makes Batman insanely jealous. So Batman MUST kill Superman because he is in competition to be the hero that people admire.
So Batman gets his hands on some Kryptonite and almost kills Superman, but at the last second Superman murmurs 'Martha' which happens to be both their mothers name, and Batman goes 'Boo hoo' and gets all tender and weepy and completely forgives Superman and then Batman saves Superman's mom which makes them BFF.
In the mean time Lex Luthor creates a monster that serves no purpose in his never revealed evil plans, and the monster kills Superman but not before Superman and Lois Lane have a tender "I love you, no I love you more" argument. and then the dirt moves on Superman's coffin so we know he is not dead.
For some utterly irrelevant reason Wonder Woman with really nice legs but too small breasts shows up and joins the battle to kill the irrelevant monster, and she shows off her magic rope, bracelets and Captain America imitation shield.
Lex Luthor goes to jail where they make a huge deal of shaving his head.
Conclusions: Batman is a complete psychopath. Superman will let thousands of people die just to save his girlfriend. Lex Luthor is a lame villain with no goals.
