We watched this first whilst we were in the middle of doing up our first house - which was nowhere near as grand as the one in the film, but still a Money Pit. We didn't laugh at all, just sat and felt sorry for the characters, it was all too true! Later, when we had finished the house renovation, we were able to laugh at it all, and how true to life many of the scenes are - living with builders around you, wondering what can possibly go wrong next, the moments of despair and the final triumph of having overcome it all - all very well acted out by Hanks and Long...
When we started our current renovation we had to watch again to ensure we knew we knew what we were in for, and that we were able to keep a sense of humour! My mate, who's just bought a Grade II listed building, will be getting this as a Xmas pressie - lets hope he laughs rather than cries... :-)
