This happens every scify movie I see. A group of people come up with some crazy ass plan that everybody nods their head and agrees to follow through with, but I can never actually understand WTF the plan is.

*spoiler, I guess...*

So what exactly did Kal-El's ship do? What did the earthlings plan to do to the world engine to reverse it? I see Zod survived that initial explosion, but what was the fate of everyone else? What the fuck exactly happened in that 20 minutes besides planet Earth prevailing?

Sorry if I'm just way too slow to follow these kinds of plots haha
