Well. . . . .
The Coens made some stinkers too (even Tom Hanks couldn’t save “The Ladykillers”), and plenty of other writers and directors make good films, so I will reserve judgement until I see the finished product.
I think a lot of us here automatically cringe at the thought of a lame spin-off damaging the perfection of the original, but I respect Turturro, he might be able to pull off something interesting with such a weird and flawed character.
