Query: A kitsch classic

In the world of kitsch films, there are good-bad and bad-bad music-focused movies. ... Good-bad is "Xanadu," a film which -- though reviled at the time of its debut, and vilified for daring to put Gene Kelly on roller skates and second-bill him to a two-bit twentysomething Australian singer-actress -- has transmogrified into my second-best guilty pleasure of all time ("Showgirls" is still first). Be forewarned: your Kitsch Appreciation Sensors will have to be at maximum to appreciate this film and overlook its gargantuan flaws, particularly a complete lack of acting ability on the part of Michael Beck. It also helps to be a fan of ELO and Olivia Newton-John music. This movie isn't for everyone -- you might want to rent it first before buying it here to make sure you like it -- but I consider it to be a true kitsch classic.
