Kenneth Turan, film critic for the Los Angeles Times and NPR’s “Morning Edition,” presents an ENTICING blend of Hollywood controversies, historical context, and crisp analysis in “Not to be Missed: Fifty-Four Favorites from a Lifetime of Film” (PublicAffairs). OK, he cheats a little, allowing two films to share the honors as number 55 and listing an additional 54 favorites, but he deserves to be forgiven. During 40 years as a critic, Turan has watched thousands of films. Cinephiles will find plenty to devour and to debate: Only two films — “The Godfather” and “Chinatown” — from the 1970s? Even the deeply knowledgeable but never arrogant Turan wonders whether he has made a mistake.
