Bob the Builder was always terrible, even when we were kids.
They always do these revamps with shows and get rid of what made them special in the first place (Bob the Builder losing stop motion, Rugrats no longer being babies, etc.) and then act surprised when everyone hates it. What do they expect?
He looks fine the way he is, but I think he has lost a lot of his appeal with this new form.
The stop motion animation from back when the series had begun, the large head and small body... it was a lot "cuter" than he is now with the new design.
