Of all the types of comedy, it seems to me farce has dated the most, and unless you inject it with something fresh, it doesn't work well. The original movie, LA CAGE AUX FOLLES, was no great shakes, but it didn't feel dated like this one does. The scene which sums it all up is the scene where Armand (Robin Williams) is trying to teach Albert (Nathan Lane), his lover, how to act like a man (Albert is supposedly a transvestite, but except when he's performing, he looks more like a couch). This has the best dialogue (when Armand pretends to be a football fan asking Albert how he felt about a bad play; Albert; "How do you think I felt? Bewildered, betrayed...wrong response?" Armand; "I'm not sure."), but also a telling scene when Albert tries to walk like a man, and asks Armand, "Too swishy?"
The entire movie is too swishy, and the worst offender by far is Nathan Lane, whose performance screams, "LOOK MA, I'M ACTING!" Robin Williams, in a more subdued role, is pretty good as Armand. Gene Hackman, as the conservative senator, doesn't go over-the-top performance wise, but he makes his character into little more than a joke. The women actually come off the best here, with Christine Baranski, Calista Flockhart, and Dianne Wiest all being good because they avoid the flailing about that constitutes most of the acting, indeed most of the movie, here.
