I know criticism is easy but that doesn't mean you can't be particularly good at it. Jeff Stark, the associate editor of Salon Arts and Entertainment, is very good at it.
Read his article Rock is dead and well at the MTV;; Video Awards at Salon. Sure, criticizing the MTV;; VMAs for being low class and artless is kind of like criticizing *Nsync for pandering to teenage girls, but this is still a fun article.
A representative sample (italics mine):
Durst of Limp Bizkit (do not follow this link) said something about being in “the world's most hated rock band.” This is the same lame outlaw posturing Metallica specializes in. How unpopular can you be, Fred, if you're up onstage getting an award from Viacom?
