I have to say that, although I wasn't a huge fan of Vanessa Williams' interpretation, she wasn't nearly as detrimental as many suggest.
Although I would have been fascinated to know what Sondheim would have done if he directly addressed the AIDS issue, making it more metaphorical allowed for the show to resonate quite deeply after 9-11...at least for me.
I was not a fan of several of the additions in the revival (the 3 pigs...2 wolves), nor was I a fan of much of the casting (Jack and Little Red were way too young to actually allow the sexual implications of their songs to shine through). But I was a VERY big fan of Lapine's direction of act II. The original had quite a lethargic pace...reflective almost...very Chekhovian. The revival had and urgency and drive to it that was VERY affective.
Had he directed act II this way in 1988, I don't think many people would have had the famous 'second act Sondheim' problems they did.
