One Mr. Tom W. Chick has been known to say "Fuck Star Wars" as his reaction to the new films, games or, well, anything. I don't even think it has to be Star Wars related any more..
They didn't really bother me that much, but I didn't linger in the sewers like I did in Moresby and resort area. I basically shot straight through them and back through them when required. Still, I don't quite think they were the least interesting area of the game, but close.
Zoe Saldana in Colombiana is all about crawling through vents. It's actually one of the movies dominant themes, if you can believe it. Watching it, I found myself willing to give vents another go.
One man's sewers is another man's oubliette, which is to say: "Them is some fancy sewers!"
Personally I like the sewer area. It's one of the most graphically pleasing areas in the game in my estimation. Yeah you can get lost in them but that's part of their mystique :D
