Robert De Niro and Ben Stiller in Meet the ParentsMEET THE PARENTS

I'm not sure that any movie genre is harder to critique than the Sitcom Disguised as Feature Film. You know the sort: a comedy, usually with faux-dramatic undertones, filled with likable actors playing likable people (even the antagonists are more pesky than dangerous), where the characters' dilemmas are sorted out neatly in under two hours, and with no serious harm coming to any of them in the end. The dialogue is moderately witty, the physical gags are predictable but amusing, the lighting is overly bright, and the score is bouncy, with moments of sap when the characters show their "souls." What's to discuss? You know going in what to expect, and when the film in question is pulled off well, as Jay Roach's Meet the Parents is, you leave feeling serene and comfortable.
