I'd chalk it up to having different expectations, not unrealistically since I obviously saw previews mind you, just kind of what I wished, but at the same time I just can't appreciate that kind of level design even for what it is. It's just personal taste at that point.
I also had the history of previously getting the disappointment that was Doom 3 after a long wait...then waiting fucking 12 years or whatever for another game I found thoroughly disappointing. That'll sour anyone I think haha.
Many people, including Romero and Carmack, agreed that Doom had a heavy and obvious Horror aspect to it even outside of the obvious textures. This was really played up in PSX Doom, PSX Final Doom, Doom 64 and then (misguidedly in my opinion) Doom 3. Even going back to the original PC version one can see and hear that in the soundtrack, only a certain percentage are 'Metal' tracks and a large percentage indeed are MIDI attempts at atmosphere. I mentioned it before, but in my head the logical step would've been to continue that lineage for the reboot in ramped up to 11. The PSX versions and Doom 64 obviously had some graphical 'cheese' to contend with but with current gen graphics, it would've been amazing to see this direction blossom into something truly horrific, claustrophobic and evil.
There's also a sense for me that my favorite gaming franchise, and literally PSX Doom is my favorite game of all time, just blew it yet again after all that wait and it's depressing yeah. I've said it before but I'm obviously aware I'm in the minority with that opinion but it's still worth discussing.
