I think part of it is that the people running the americans networks are a bunch of politically minded twits that don't have a fraction of the humor of a primate trying to get high by sniffing poo.  Thus the things they think are funny are about as drole as a sloth watching paint dry on a humid day.  They wouldn't know funny if someone nailed it to their genitalea. 

The other part of it is they'd rather produce something that scores wells than watch it themselves and see if it's humorous or not.

American movies can still be funny though.

WARK!
