I read through that UltraBoris review, and I agree with most of it. I personally have always thought Master of Puppets was a mediocre album. Even when I was getting into thrash and heavier metal I never cared too much for it. I think saying the album killed metal is being really overdramatic, but I understand that people calling it the definitive thrash album is far from accurate. It is just one of, if not the most popular. I agree that it serves as a gateway album for metalheads looking for heaver, faster stuff, so that is cool. But I just could never get into it.
