"American Masters: Bob Dylan: No Direction Home," 9 p.m., PBS; concludes Tuesday. The notion of profiling Bob Dylan seems both fascinating and futile. Here is someone who keeps changing his persona and his version of the truth. How can we watch a biography of him? Just settle back and enjoy the scamp-like quality. Relive some of Dylan's more audacious moments. Watch him confound friends and toy with clueless interviewers. Savor a story that goes from a frigid Hibbing, Minn., to Greenwich Village and beyond. Director Martin Scorsese has fresh interviews with key people — including lots from Dylan — plus a rich assortment of concert footage. And as Dylan performs, we can catch some strange, scattered moments of genius.
