Weeds, the new Mary-Louise Parker television series, has been running in the U.S. on the Showtime cable channel since August. It premiered here in Canada last week on the Showcase channel. It’s a very compelling show and is worth watching: Parker is excellent, backed by a strong supporting cast; the conceit of the show — newly widowed suburban woman becomes a drug dealer — isn’t as far fetched as you would think, and it’s a useful lens through which to look at middle-class America. Next episode is Wednesday at 10:00 p.m. Eastern.
