Politics aside, it's not that different from a director like Joel Schumacher, who made some really great (IMO) films like Flatliners and Falling Down. But then he made the Batman movies and that's all people remember him for. And his career has never recovered from it (and some of his more recent efforts have been even worse). A shame really. He was a good director once.
Ok, I am a bit more awake now, and can now reply to this statement on JS.
What this reads like to me, is propaganda, with no real basis in reality.
JS's career did not suffer because of B&R, that is just the perception you have because you spend a lot of your time on these boards, with folk bashing him all the time.
You are very off if you think that people in the general audience, ie in the real world, even know who JS is.
His career carried on in much the same way as it did before B&R, financially and creatively.
Big stars and respected actors worked with him in the years immediately after B&R, Phillip Seymore Hoffman, Robert DeNiro, and it was Schumacher's Tigerland that got Hollywood to take notice of Colin Farrell.
I guess you, like a lot of people on these boards, have an axe to grind against JS, but no matter how much you wanna believe it, in the real world, where opinion counts, the fanboy rantings do not matter one jot.
