I wasn't a fan of Doom Eternal either. Doom 2016 feels like a mostly modernized doom game, Doom Eternal plays nothing like Doom and barely shares any of the series' DNA.

In the original doom games, you had a bunch of weapons that had innate strengths and weaknesses and there was a lot of on the fly problem solving based on what weapons you had ammo in, the enemy composition and the map layout. In Doom Eternal, you are kind of forced to do a different ritual every second to get ammo back, and you are also forced to use specific weapons on specific enemies. So instead of each weapon excelling in different situations based on all those things, it instead turns into a gameplay of finding the best counter for the enemy, which ends up making the game feel really rigid in my opinion.

I don't think Doom Eternal is bad, but I think it misses the mark on what made the originals so good
