Rep: The Genetic Opera is a great Blu Ray movie, and I wouldn't compare repo men to it. That's bad.
Genetic Opera had a plot, a secret, a bad guy, a good/bad guy, a dying little girl, a company that re-posessed organs, and a bad-*** lady who could project images with her eyes and sang opera... oh and did I mention the whole movie is a rock opera? I'm pretty sure that song at the end won some kind of award, and when the little girl cried at the end after that 2nd to last ballad, I almost cried. AND IM A MAN! A MANLY MAN!
Repo Men: Two guys work for a company, one guy goes "woops" then the company is all like "here's some **it" and he's like "no thank you" and they're like "too bad." Then the company did not give him a break because he worked for them for some reason and then I turned the movie off.
It's definitly not a remake, and it borrowed an idea, that was already good enough.
