Doom 3's gameplay was a victim of the PC technology of the time. Recreating the Doom/Doom II experience with all of those enemies and items on the screen at once simply wasn't possible with the hardware available at the time of Doom 3's development since Carmack was pushing the game to have leading edge visuals. Sure, he could have made the game less demanding like Serious Sam and recreated the original experience, but that is not what he and id wanted. It also wouldn't have sold a lot of hardware upgrades like Doom 3 did which is what hardware vendors wanted.
However this is now 2012, and one big reason this re-release of the game is such a letdown is that Bethesda/id didn't use the opportunity to make the new "lost" missions in the game take advantage of the prevalent graphics hardware of the past eight years since Doom 3's release to recreate the original Doom gameplay experience in the Doom 3 engine.
