If you are going to listen to metal (at least for me) you have to have a perkier mental high as opposed to a heavy body stone. Otherwise it just irritates. Pantera is good stuff though. Metallica Black Album is the way to go for a "beginner" metalhead though. It's got enough "pop" in it, that its digestible, but its undeniably metal. I can see how if you were high and weren't into metal and someone put on some cannibal corpse how you could be really turned off by metal. It's an aquired taste.
