Sicko (DVD)

Optimum Michael Moore's latest documentary focuses on the iniquities of America's extortionate health-care system, and presents our own NHS, among other countries' equivalents, as a preferable alternative. The surprise is that 'Sicko' has almost none of the animated segments or the old-movie montages which are Moore's stock in trade, and the man and his baseball cap don't appear on screen for a full 45 minutes. 'Sicko' is still a lucid, wry polemic, and it's more at home on DVD than it was on the big screen, but it doesn't feel as lapel-grabbingly vital as Moore's other work.
