Like high school bullies, George Bernard Shaw is all talk. But what glistening, dangerous talk, stuffed with politics and metaphors, disgust and poetry, curlicued wit and endless windbaggery. The best of the Shaw plays staged in recent years by the Kansas City Repertory Theatre, last October's Man and Superman and benefited from actors up to all that talk. Playing Jack Tanner, a firebrand susceptible to the very love he rails against, Kaleo Griffith spat and raved with sloppy poise, somehow making all that talk equal parts intelligible, believable and hilarious while still seeming more flesh and blood than a book on tape. In the end, he even made us feel for his Tanner, a man prone to statements such as "The true artist will let his wife starve, his children go barefoot, his mother drudge for his living at 70." Griffith's art was so true that we're tempted to call someone to check in on his mother -- or any of the women in his life.
