Pandorum (2009).
How the hell did this film flop?
It's visually amazing, has great action sequences and lots of interesting ideas.
I think the orcs moving in weird J-horror fast motion was laughable. Killed the flick for me.
As for "narrative flaws" the explanation "they gave the people drugs to speed up evolution so they became Mad Max Orcs!" was some of the goofiest sci-fi-talk I've ever heard.
