Even 20-odd years after the fact (and with it's late-70s sexual revolutionism looking humorously dated these days), Carla Lane's 'Butterflies' remains one of the freshest and funniest sitcoms Britain ever produced. The story itself is relentlessly simple -- a stifled housewife's yearning for more in her life is complicated by a distantly ironic husband, two sex-crazed still-at-home sons, and the romantic attention of a wealthy playboy whose desire revs up the more undesirable she feels. But it's not the plot that makes 'Butterflies' great so much as it is the opportunity that that plot gives Lane to explore Ria Parkinson's world as it slowly collapses around her, and it's impossible not to see a little bit of oneself in the sometimes-hilarious, sometimes-sobering struggles of Lane's memorable characters as they attempt to survive the small anguishes of day-to-day life. Smart writing and great performances all around.
A few years back, 'Butterflies' would show up in late-night rotation on PBS in the states and Canada; if it does again, catch it.
