“A Complete Unknown” probably won’t please Dylan purists or anyone, really, who’s a stickler for documentary facticity in fiction. Those admirers are bad, but Pete and the folkies can seem worse because they’re dogmatic and because, well, they’re not cool. Chalamet does look cool, if not as otherworldly as Cate Blanchett in Todd Haynes’s 2007 film “I’m Not There,” in which she also plays Dylan around the same transformational era. Neither look, sound, feel as cool as Dylan once did. As this movie underscores, he is very much a beautiful dissimulation, and sometimes there is nothing more authentic than an entertaining con.
