Bad directors SHOULD fail. Because they are bad.

Good directors can put out shit but redeem themselves with other works. But Rollerball, Jupiter Ascending, Batman and Robin by Joel Schumacher, THOSE movies end a career.

Martin Scorsese gets away with 'Hugo' because he is fucking Martin Scorsese. Guy Ritchie gets King Arthur. Does Don Hall get another shot after the financial abomination that is 'Strange World'?

Weird and difficult place to be sure.
