the Soon-Yi thing was disgusting, but it is possible to evaluate him aside from that - to me he has just made too many bad and pointless films, with a few gems - What's Up Tiger Liillie, Take the Money and Run, Annie Hall, Sleeper, Radio Days, Sweet and Low Down (I think was the name) - and he was never a leading man, though he tried to cast himself, and it became harder and harder to accept him in that role -
years ago I played a party for William Styron's 65th or 70th birthday, in Litchfield Connecticut, not long after the whole Farrow/Woody/Soon-Yi thing happened. In the middle of the party Farrow walked in, and I looked at the band (Harold Danko on piano, Jeff Fuller on bass) and said 'let's play Woody 'n You." They declined to do so.
