After Ricky Gervais' performance, many critics and old stuffy white dudes criticized the hist for being too lewd, crude, and actually funny. These are the same people who hated on Chris Rock in 2005 when he hosted the Oscars. Yet these same people criticized Jon Stewart for not being funny. Well make up your mind, do you want these people to be tame or to be funny? You can't have it both ways.
I personally loved Gervais (and Rock a few years back). These award shows are a bunch of narcissistic blowhards patting themselves on the back. God forbid we can laugh at them while they do it.
