But The 100 Greatest Looney Tunes Cartoons isn’t an argument about the essence of Looney-Tunesness, or even about the aesthetic standards by which these surprisingly tenacious bits of cultural ephemera should be judged. Beck declines to rank the films, offering them instead in alphabetical order, and restricting his own contribution to short plot summaries and little “Jerry Says” callouts. The heavy lifting of critical evaluation is left to a motley crew of guest commentators, who participated in an unscientific online nomination process, or have industry insights, or are just giddy fans.
