...it didn't.

Honestly, I'm not usually one to complain about art, but the comic looks like storyboard sketches that never quite got fleshed out. Characters bear a vague resemblance to their movie counterparts, in most cases.

Storywise, it explains some things in the movie but it isn't the epic backstory I thought I would get. A lot happens without anything really being explained. It somewhat furthered my sense of the world, but it didn't give me any "ah-ha!" moments like when I'm reading 40k lore or something, which I guess is really a lot to ask for. I read all 3 comics and watched the movie that evening, so if anything was supposed to stick out more than it did, it really didn't.

All in all, I still love the movie - beautiful mess that it is - but I'm probably going to stop telling people it's supposed to make more sense if you read the comics.
