Ah where is your sense of humor? Megadeath loses your respect because they decide to have a little fun? Come on =) It was entertaining, not laugh out loud, but entertaining. It certinally wasn't a waste of my time.
Don't get me wrong, I enjoy Megadeth from time to time. I just don't see the point in something like this. The plot sucked (even for a cartoon), it just seemed like an excuse to do a music video. It wasn't funny, and wasn't particularly entertaining. It wasn't even one of thier better songs.
