I've never liked Doom, even as a kid. But after finally playing through the entire game, I can say that I respect it. Definitely innovative for the time, and with expertly crafted design and gameplay as well. But its aesthetic is kind of goofy and corny in a way that detracts from the experience for me. Still, the gameplay holds up really well, and the goofiness of the synthesized instrumentations and pixelated horrors end up being somewhat charming in a retro kind of way.
