People, people, the core concept of Repo Men is not original to the Genetic Opera movie. A very similar concept was featured in the Monty Python movie <url=http://www.youtube.com/watch?v=aclS1pGHp8o>The Meaning of Life (and that Python clip even featured in the movie itself; Law and Whittaker were watching it at one point). Also, it's an idea which requires the tiniest amount of creative thought to approach, given the current spirit of the times. I mean, think about it: foreclosures, repossessions, economic turmoil...
Extending that to our bodies, beyond our material possessions is not a tremendous logical leap by any means.
The biggest failing of this movie was a lack of strong direction--it appeared rather unfocused to me. However, I did love the ending, which struck me as incredibly similar to the ending of Brazil, directed by Terry Gilliam It struck me as appropriate to this film, however, and not a ripoff. Although the events were pretty similar, the themes and context concomitant were differentiated enough for it to feel more like an homage, or unintentional congruence, rather than copycatting.
In closing, it was a plenty adequate movie, even taking the gore into account, which there is indeed a lot of (but, in fairness, the film's core idea would have fallen flat on its face if there hadn't been a lot of gore).
