Music critics are all over the place and often spend more time trashing or praising the artist in their reviews rather than actually saying what was good or bad about the album. A lot of them are also so far up their own asses. Half the music reviews have barely any substance to them once you cut out all the attempts to sound intelligent and deep.
I don't pay too much attention to gaming critics, but I think they're generally okay. Sometimes I spot some dumb ones though.
Game critics. They focus on the meat, the game. The console and such. They may skew by possibly preferring a console or series to another, but are usually spot on.
Movie critics and music critics start bashing the actors and artists instead of the actual art they are displaying. They focus too much on the drama.
