Batman V Superman: 13 Biggest Blunders Zack Snyder Makes That Completely Ruin It

3. Doomsday Is Nothing More Than Deus Ex Machina

Mentioning Doomsday - in terms of his origins, impact on the plot and the fact he's in the movie at all - should have counted as a spoiler, but he's in the trailer, so is complete fair game. And what a mess he is.

I don't necessarily have a problem with him being a product of Lex Luthor experimenting with General Zod's corpse. It makes sense in the world (ish) and is a nice little meta parallel to the character's comic origins; he was created by DC with the singular purpose of killing Superman, and that's the exact reason why Lex has crafted his "devil". And that he could be best described as Dumbsday, looking to have the intelligence of a Lord Of The Rings cave troll, is likewise not a major issue; the important element is brute strength. He's also fairly well set up, teased throughout the movie's first half.

The problem is that in the movie he's for the most part an empty character used as a deus ex machina to bring the Trinity together, never becoming more than a grunt. There's a vague attempt to bring some of his key comic book traits to the screen, but they're disregarded a moment after they're raised, with characters explicitly ignoring things they've just learned as they take him on.
