Oh no, it's Survival Horror Resident Evil vs. Action Resident Evil all over again.
I'm going to say that I'm pretty hard into the "I want my Doom to be DOOM, dammit" camp, but I still appreciate what they tried to do with 3. The problem, as many have said, is that they're obviously trying to go for some sort of System Shock vibe, but the only thing they could seem to think to do for a majority of the game is monster closets. It quickly became predictable, and lost any sense of fear that they were trying to go for. Having a wall open up from behind when you are in a corner or a tight corridor so a guy gets some free shots on you is not scary, it's frustrating. Sure, the Dooms beforehand had monster closets too, but they weren't trying to scare you. It was a surprise encounter to drain you a bit, usually after you found a really good item. There was pretty much always room to maneuver and avoid damage.
I've certainly got no problem with them, or any game company, trying to do something different, but they have to convince us that it's worth it. A prettier, but not quite as good, version of System Shock 2 just ain't going to cut it.
