I get what you're saying. I kinda feel the same with Black Metal. My advice would be to go listen to a bunch of the classic albums, and if none of it takes your fancy, leave it alone. You can't force yourself to like something. Maybe you'll like it in a couple of years. I'll list some benchmark albums that imo should get you into it if you're going to:
Pestilence - Testimony Of The Ancients
Deicide - self titled
Entombed - Left Hand Path
Death - Spiritual Healing
Morbid Angel - Blessed Are The Sick
Obituary - Cause Of Death
Carcass - Necroticism: Descanting The Insalubrious
