Will Smith goes on stage at the Oscars and hits Chris Rock then verbally threatens him from his seat

You’re not wrong. Let’s just say he disappointed me and I don’t care to be reminded of it. I don’t watch much from Robin Williams either. I don’t like thinking about it and it’s the first thing I think of when I see him.
I agree with your sentiment about Robin Williams. It took me a while, but I got over it and back to enjoying a flick with him in it every now and then and yeah, it's sad when reminded of it, but not gonna stop me from watching.
