A charming old-fashioned romantic comedy for literate adults, the kind they don't make anymore – or too damned infrequently. This soufflé-light concoction rises based on the natural chemistry between its two veteran stars. Everything else, including a silly turn by Keanu Reeves as a young doctor besotted by Erica, is window dressing, but with Nicholson and Keaton in such rare form, who cares?
