Query: Not For Literalists

"If only . . ." The film is permeated with this feeling of frustration and regret. If only Callas had been properly filmed in performance instead of leaving behind one creaky black-and-white version of part of "Tosca"! If only her voice had lasted a few more years! If only her friends could have done more to pull her out of her shell at the end! Never one for understatement, Franco Zeffirelli gives lavish expression to his deep sense of loss by fantasizing on what might have been. Does he succeed in conveying to younger generations what the world has lost? Or is his creation both too stagey and too personal? It worked for me, but probably not for anyone insisting on factual accuracy.
