The TV series Metal Evolution is 6 episodes too long (11) & spends as much time on glam & grunge as thrash & on Poison & Nickelback as Metallica, etc. Anyone who doesn’t care about heavy metal is going to find more than two episodes quite enough, and anyone who does is probably going to know way more than anything provided in the series. (The questions asked are just not good enough, the biggest problem being that actual pieces of music are almost never discussed.) I don’t CARE if Nickelback plays more interesting stuff live than evidenced in its radio hits: its radio hits are terrible (although I do find “Bottoms Up” a half-decent example of an irresponsible, excessive-drinking song), and Creed was mostly just warmed-over (and thinned-out) early Pearl Jam.
