It's weird. Part of me wants to say I don't blame him, but especially on something like the Simpsons SO many writers have lent their voice to the show over the years that it's almost arrogant of Groening to take complete ownership. That sounds a bit harsh, but I feel like it stopped being his a long time ago and he should embrace the opportunity to see what UC can do with the property. Not saying him pushing them is a bad thing, but that doesn't mean it's always good either.
