brilliant? maybe...
I must admit I have only seen the third season, as it was recommended by a friend. And now, I'm watching the fourth season as it is aired.
There hasn't been one episode that was just OK. For a series to deliver in EVERY episode is a rarity. And for a show to hook someone (me) this late in the game is both atypical and impressive.
While constantly poking fun at the hypocrisy that makes up so much of our society, and having an endlessly twisting plot, Weeds will hopefully never cease to impress.
