One can’t help but think of actor-director Roberto Benigni as a poor man’s Woody Allen. Or perhaps he could be described as Woody Allen lite. To some, Benigni seems a genius, while to others he’s the flaky guest who rattles off a dozen terrible jokes and one zinger. His eighth film, “The Tiger And The Snow,” is essentially “Life Is Beautiful” set in war-torn Baghdad. And once again, the talkative Italian’s sheer exuberance is going to win you over once in a while, even if it takes multiple attempts to do so.
