Stupid film but I get it...
It's supposed to be satire but it really is quite lame. There are better satire films out there like Election, Romy And Michele's High school Reunion, Pumpkin just to name a few.
I think the plot being so focused on... well.... competitive butter sculpting, actually made this film almost unwatchable. I mean, I get this is the point of the movie, it's supposed to be ridiculous but I think the ridiculousness can only get you so far until a film just becomes dumb.
However, in defense of this movie I will say that I never knew people actually did this. Apparently it's a pretty big thing in some countries/states. There are some very impressive pictures of butter sculpting on google and there's a wiki article about it...
