The movie is built around Loris, the character played by Roberto Benigni. who delivers his best performance. He is 100% believable in this role. The movie has almost all classic ingredients of a great comedy and they work.
Roberto Benigni's character captures that facet of most of us men at some point in our lives. A lazy and not so well organized guy, far from hansom looking, who'd like to have a lot of women and money, but is not yet successful with either, improvising plans and schemes to get them fast and easy, getting himself in trouble instead, and plunging into more trouble the more he tries to sort things out.
Eventually the police is after him (the police surveying tape is hilarious), and as goofy as Benigni's character is, the police match him with style. They dispatch a bait to unleash the monster within, and Loris has to go great lengths to avoid unleashing that monster =))
Watch this movie in Italian with subtitles, don't let some lousy dubbing spoil your experience.
