Why am I disappointed by the graphics? Very dark, not true to "Unreal Engine" IMO as primarily a PC gamer.

I don't do alot of reviews,so I'll keep this brief. I enjoy the game, but I find the graphics disappointing. I'm using an HDMI input to a 1080p 52", and compared to other PS3 games the graphics look flat, dark, and uninspired. Perhaps it's because I've been playing PC games such as Vanguard, HL2 ep.2, and the UT3 demo that my expectations are too high for a console, but I've played several excellent looking games on the ps3 so I know it's capable. Also, I am surprised to know that it uses the UT3 engine. Gears of war looked very good for a console game, and UT3 is quite impressive, but this game lacks a certain crispness that I had expected, just as when you watch standard TV on a HDTV and it looks "grainy" and flat.
Graphically, one other disappointing note is that when you go to Video options, it just gives you a white/black/gray scale, and tells you to adjust your monitor!!! Uhh, NO! I spent a long time adjusting my TV settings, and to change them and change them back for one game is unusual, when typically games have brightness, contrast, and/or gamma adjustments built in to the game themselves! I found that lack of a feature almost offensive to me as a consumer and AV enthusiast.
In conclusion, the game is fun, my gripes are technical; it's a fun game that seems like a quick port from the PC. In hindsight, I wish I bought it for the PC instead :/
