I was disappointed that they went with the tired old grunge look for the spaceship-- I'll never understand the appeal of a future that looks like an old factory basement.
I think it is to give a realness with a lived-in feel to the created worlds in sci-fi and fantasy genres. I think the flip side of that is the super clinical brand new everything (and thus unreal) production design/art direction.
like this thread:
Should the future look "Futuristic?"
my post there
summed up my thoughts on it mentioning numerous movies art direction/production design.
