According to John Carmack the game engine wasnt even close to being done when that demo was shown. By the time doom 3 is released it is going to look much better, and run much better to.
So hold off on juding the game until you see the final version. It isnt fair to just blow it off on a alpha build that was meant to show only the graphics on a very incomplete game engine.
