Query: Funny and bittersweet

We enjoy Christopher Walken in comedies, and this movie proved to be as funny and heartwarming as we thought it would be. He's hilarious (again) as the wacky character Nat, the ultimate con man who makes his way through life without paying money for things, for ANYTHING -- although he rewards helpful working people with product/service gift cards and "freebies" (the equivalent of cash). Would you want to be Nat? Not really! But do you like Nat? Yes, really! Great movie!
