Weeds in its first three seasons was an excellent show—it was well-written, clever satire with multifaceted and funny characters. Its send-up of the rhetoric and culture of suburbia was funny and pointed and coherent. Celia was a hilarious and capable antagonist, and I loved that the older het white men on the show—Doug, Andy, and Dean—were strongly characterized as inept and lazy. In contrast to the class and race privileged characters in Agrestic, Heylia James and her nephew Conrad Shepherd, the pot dealers who gave Nancy her start in the business, were funny, sympathetic, and competent. They were easy to root for, while Nancy made irresponsible decisions by the dozens. Heylia and Conrad took themselves and their ambitions as individuals seriously, and handled themselves and their business adroitly.
I'm not alone in thinking that Weeds has fallen hard in recent years. The basic thesis of the show in its fourth and fifth season seems to be "everything falls to shit, and Mexico and Mexican folks are every awful stereotype you've ever heard." All but the most clearly and slowly spelled out motivations of the characters are completely unintelligible. It's not very funny, and doesn't put sexism or racism or classism in any kind of critical context. The greatest indicator of this steep drop in quality is the complete and total erasure of Heylia and Conrad. Much to the show's detriment, these two fine characters have been abandoned, literally never mentioned at all after the end of the third season.
