So, I finally finished this game. It took me almost 17 months. I kept thinking the game was almost over, and then there were another five levels.
Overall, I give it no more than a 5/10. I was as far down as a 4/10, but the last boss ended up being kind of epic (after initially being annoying). Maybe at times I got as high as a 6/10. My experience in the game felt weirdly inconsistent. At times it was enjoyable, so I didn't hate every minute I was playing, but there were too many clunky aspects that took me out of that enjoyment and kept pushing me away. It was also too long, probably padded out by the platforming, and had a couple pretty boring levels.
I feel like pretty much every change they made compared to Doom (2016) was a step in the wrong direction. The platforming sucked. Too little ammo even after fully upgrading was obnoxious. I can see how the changes may have made the game have more depth and require more "skill", but in this kind of game I just want to get in their blasting with whatever weapon I want. I don't want to constantly run around looking for ammo. It just ruined the enjoyment for me.
As mentioned in my quoted post, the lore was utterly ridiculous and I stopped even bothering to read it about 1/4 way through. It made so little sense that they'd have been better off just leaving it out in my opinion.
On the plus side the visuals were awesome. The boss battles felt pretty epic. And sometimes the combat was still fun like Doom (2016). But on the whole I didn't like the game and don't recommend it.
If they come up with another Doom I probably won't be buying it unless the word is it's gone back to be a lot closer to Doom (2016), which I enjoyed. Hell, I even enjoyed Doom VFR. This just didn't have the same magic.
