When he puts up some of his own money and starts drinking, you can see he's having a good time. There's a fair bit of avoidance of reality. Did he expect the predictable answers he got in return. He asks some polite, but point blank questions to gamblers and various staff members. I question if the Hilton imposed rules or a contract with him in able to film. You can definitely sense he's trying not to judge, but he hardly looks comfortable being a bystander. Louis has a hard job straddling a fine line. They can afford to in all cases, but it's gone from being entertainment to an addiction. He follows around (some hardcore) gamblers and you get an idea from most of them why they do it. You do hear serious sums of money being lost however. You never glimpse any heavy depraved sadness as Louis strolls the Hilton Hotel & Casino property circa 2007. The tone is generally light and pleasant. An entertaining place primarily built to separate gamblers from all their money. It isn't a heavy handed anti-gambling pic, but it does show the place for what it is. This Louis Theroux documentary touches on that point and many others as it explores Las Vegas. The odds are against you with the house edge even if certain people don't want to admit it. Everyone knows that casino gambling is a long term losing bet.
