OK, OK, let's forget about the whole money grows on tree aspect of the story and just focus on the comedy...ehh, it's alright. Unfortunately, most of the jokes focus on the different ways that Blandings is getting ripped off. Example: the guy he's paying to discover water for his well is paid by the foot, so the joke is the well digger guy has to dig over 200 feet down to discover water while the house construction guys only have to dig down 6 feet to discover a spring that ends up flooding the basement. Hardy-har-har. If that kind of stuff gets you to knee-slapping then MBBHDH is the movie for you. I kinda found it more depressing than funny.
Not a bad movie, but I think you'd better off watching GEORGE WASHINGTON SLEPT HERE which has a very similar story, but actually funny.
