Death metal (and by extention, it's brothers thrash and black metal, not to mention its distant counsins crust punk, grindcore, and hardcore) is a passionate form of music, it's all about the energy and atmosphere far more than technical ability.

Even then, there are still plenty of bands who pride themselves on the complexity of their music: http://www.youtube.com/watch?v=utqWrkVEQvI

Point is, you're the only one so far who's felt the need to take a gigantic dump on a music genre that you don't understand, don't like, and aren't even interested in completely unprovoked.

I listen to this sort of music all the time, I've ran into plenty of people like you who don't understand this stuff and think they need to berate people who get any kind of enjoyment out of it.

You don't understand it, thats fine. You don't have to like it. There's plenty of music I don't understand and I don't like (a lot of electronic music falls into that category), the difference is that I don't go around unprovoked talking shit about them.
