NNNNN (2006)

When Nat Noland begins arguing aloud with himself while creating a controversial revisionist novel about Cain and Abel, it sends the adopted writer on a quest to investigate his own birth family and discover that voice in his head might be a long-lost sibling. This bland tale is intended as bawdy farce, but NNNNN with its clunky, shticky dialogue and plodding structure (a 40-page happy ending?) reads like an outline in which Carl Reiner forgot to insert the fun. It feels heretical to call the work of a comic legend unfunny, but if his protagonist can be blasphemous, so can we.
