Two hours of upper-middle-class naval-gazing? A poison pill of nostaliga? An exericize in self-loathing? A critique of ex-hippies who sold out? Or an attempt at excusing "going straight" and embracing being a yuppie? Maybe it's all those things. Or maybe that's putting too much weight to put on a movie that's mostly a small drama about people coming together after a friend's suicide.  Starring Kevin Cline, Glenn Close, William Hurt, Tom Berenger, Jeff Goldblum, Mary Kay Place, Meg Tilly,  JoBeth Williams, and Kevin Costner's body. Written and directed by Lawrence Kasdan.
