Based on Lanford Wilson's early -- and quite autobiographical -- stage play, "Lemon Sky" is atypical TV fare. It's non-linear structure and surealistic staging might be off-putting for the average couch-potato. But Wilson is a brilliant writer, and Kevin Bacon gives possibly his best performance as a young man trying to fit into the family of an abusive father who left him as a child. This is the film where Bacon fell in love with Kyra Sedgewick, and so did I. Her sexy, tough, tragic performance raises the question of why she never became the major star that her talent deserves. I taped this from PBS, and showed it to dozens of my high school drama classes, and they loved it every time. I wish it were available on video.
