WOW!
This movie was just soooo crazy! I mean...it just flashed in the front of my eyes. The Dad is coming home from work and then he's just GETTING CRAZY! Anyway, that madness also has a good point, and it really is true- sometimes dads come home from work and they're decided to do something with their life (for example, be a good dad, have a good time with wife and so on) and they're doing everything to make other family members to understand that. In the beginning, they're sooo suprised, and, may-be the ways that the dad is using may be very suprising, too. But then the family and the dad find something they all like to do and then they do it. I think that is the point of that movie.
I have seen really-REALLY good movies without good point, at it makes them not really good, if I won't say - bad. This one is good.
