This is one of the most subtle comedies to come out of the UK. Not as brash or slapstick as a lot of others. Lots of character development, especially the lead, Ria, played by Wendy Craig. Every middle aged woman I know that has seen Butterflies relates to the frustrations that Wendy portrays so well, not just the stale marriage and longing for romantic adventure, but also the idea of being a stay-at-home "kept woman". The extra kicker is that she isn't even a good housewife. Lousy cook etc. Luckily, her long suffering husband has learned to cope with her, keeping his head down, and advising his sons to "act normally" as they listen to Ria's frustrations pour out. The whole supporting cast was so well chosen, from Ria's erstwhile lover to the house cleaner who takes the sons girly books home for her husband to read. Brilliant writing and direction. Not to be missed by anyone over 40.
