Query: The most watchable series on TV

I've followed Weeds all four seasons and I'm consistently entertained and impressed with the caliber of the acting and writing. I've always appreciated the balance between the literary and the lunacy.Season four took a definite departure from the safety of Agrestic...a departure to a California border town near Tijuana. Nancy's (Mary-Louise Parker's) involvement with the dangerous/sexy mayor of Tijuana (Demián Bichir) was a nice addition, as was the twisted relationship between Celia (Elizabeth Perkins) and DEA Till (Jack Stehlin), who brilliantly walked the comedy/drama line. As always, the comedy trio of Andy (Justin Kirk), Doug (Kevin Nealon) and Dean Hodes(Andy Milder)totally paid off. As for the kids Silas (Hunter Parish), Shane (Alexander Gould), and Isabelle (Allie Grant)- they are proving to be fine young actors, holding their own in every lovely scene. I'd say that season for is a must have for any Weeds fan, future or present.
