No group is spared from the movie's mockery, including the elderly, homosexuals, racists, and more. Despite this, you could argue that the movie actually promotes a message of peace and understanding among warring nations -- and there's even a secondary message of love crossing barriers.
Positive Role Models & Representations
Lots, but it's quite cartoonish and generally played for laughs. For example, Zohan can jump from rooftops and land on enemies without getting hurt, he gets shot at without getting hit because he stops bullets with his bare hands, and he can successfully battle loads of gun-equipped assassins. Other characters brandish weapons and missiles, and there's a fair amount of kicking and tossing people around. In one scene, someone cuts off Zohan's hand, which he then uses to kill his tormentor.
Plentiful, and plenty crass. The film begins with lots of cleavage (and has plenty more throughout), punctuated immediately by a close-up of Sandler's naked backside (which viewers see again later). Incessant sexual jokes, suggestions of Zohan bedding all sorts of women as part of the "hairdressing experience." Sex scenes include some group activities. Lots of lewd references to body parts, sexual activity, etc. A woman's naked backside is visible in one scene in which intercourse is implied. Zohan gives his clients "happy endings."
Language includes "goddamn," "s--t," "jackass," "screw," and more.
Signage everywhere, from Zohan's favorite fizzy soda to Phantom's fast food restaurants. Also, clear logos/signs for movers, stores, malls, and the venerable Paul Mitchell hair salon.
Ease of Play
Some social drinking, primarily at the beach parties Zohan hosts in the beginning of the movie.
