It's not great, I agree that much.
But really when you see examples of bad rolling shutter it's when somebody has a cheap HD camcorder that they are waving about as quickly as possible to really show it.
So many films are being shot now on the new digital formats and seem to be getting by, despite rolling shutters. Personally though I'd rather see a film that's been shot on negative over one shot digitally, any day of the week.
