The funniest humour is humour that tells it like it is. Jack's confrontations with his kids' school staff and other parents, and their outragous militant "faux sensitive" attacks, are painful to watch because we live with them in real life. Every one of them has a ridiculous shield of political correctness up around them, and they use it as a weapon, thus completely undermining how "sensitive" they claim to be. Jack calls them out on it, saying at one point, "All you care about is not getting in trouble". The obnoxious 20-something who takes over their company is exactly the tiresome, lazy arrogant twit we all dread as a new boss - has never gotten his hands dirty, never worked a day in his life, has been taught by his mommy that he's "special" so he can treat people like dirt. Unfortunately, about 2/3 of the way through, Jack's "epiphany" ruins the whole thing. His wife shuts him out because he has "anger" problems. No he doesn't. He doesn't hit people, wreck property, throw people out of their jobs, sit on his behind while others do all the work, or torture his schoolmates or coworkers with holier-than-though attitude. He calls people names somertimes, and he yells sometimes. That's about it. Otherwise, he's the most honest, hard-working, fair person in the whole story. It's sad that the movie goes south by having him "change" to become a gutted namby pamby shell of his real self. That is a HORRIBLE thing, but it is presented in the film as though he has reached some successful peak.
