The Wire: If You Haven't Watched it, Watch it; if You Have, Watch it Again

Admittedly, there are some gaps in my television watching, I haven't seen Lost or Mad Men, but for my money the third and forth seasons of The Wire are some of the greatest television ever made.  The series stands alone as a critique of society.  At every level the failure of institutions is examined whether it's drug gangs, the police department, city government, schools, the white working class, or newspapers.  It is because of this biting criticism that The Wire is more relevant than ever as a social commentary.
