Carnal Knowledge-- Jack Nicholson and Ann Margaret go the way of all flesh in this bizarre and pointless chropnicle of developing sexual awareness. Art Garfunkel maundered his way through the film just like he's maundered his away through his recent songs while Ann Margret provides the jiggle interest. Nicholson is both effective and repulsive and the ending is a masterpiece of peverse nihilism. In short, an interesting waste.

Singing in the Rain--the classic American movie musical with Donald O'Connor, Gene Kelly and Debbie Reynolds oozes cutness but manages not to be cloying. You know it's all Hollywood so sit back and escape. Our heroes sing and dance their way to glory, the music is wonderful, and the dance routines are geniunely original and entertaining, no Busby Berkely wedding cake horrors. You really should see if just to say you have, and besides, it's such good clean fun.

The Cheap Detective--Neil Simon keeps those pots boiling with another patently bogus ploy to unite famous detectives and get them to satirize themselves. Peter Falk is no Bogey, however, and nobody else is who he is supposed to be either. The plot is some clone of the Maltese Falcon, The Big Sleep and whatever else. Puffed up with hocks and the usual empty calories that Neil Simon spoons out so handily this might better have been titled The Big Turkey or The Maltese Sleep. Go see the originals.

Jaws II--Just when you thought it was safe to go near the movie theaters again. Wrong. A poor second effort, with the usual predictable results. Bring your lunch, but better yet, bring all those greasy little dollars somewhere else. The sequel complex should not be encouraged. Close Encounters of the Third Kind--A major disappointment. A totally boring, over-long, overblown saga of our first communication with extraterrestrials (actually, it's not the first, as anyone from Jablib, Wisconsin, will tell you). Neato special effects, and a nice job by Richard Dreyfuss in a stupid part, but it should have been two hours shorter, and that goo-goo eyed little kid has got to go. Best scene: Dreyfuss's interrogation by--that's right--Francois Truffaut, who should have known better.
