Too much bee chasing.
I think the bee should have started the chain of event leading to the destruction of the house, but not be in every single episode. Watching Rowan Atkinson trying to kill a bee is not that funny, watching him destroy the house and trying to put it back together is funny.
The most disappointing part was when he realised the car was ruined and instead of trying to fix or hide the damage, he went after the stupid bee again.
