I have never found him funny. I find him so unfunny that I have not seen any of his movies. I used to watch "In Living Color" and Carrey was always the least funny guy on there, IMO. I don't care for comedians who are manic all the time. Didn't find Robin Williams funny, either.
I found Robin Williams being un-funny getting old as 1990. It was the same old schmiel after awhile, what was so funny I would ask when it was the same old act over and over?
When he did Aladdin when Disney was still a decent company everyone oohed and ahhed about how great he was and Williams spoke publicly that Disney didn’t pay him enough, so they gave his a Picasso painting he poo-poohed. I found it sort of ruined the film because it sounded like he was on massive amounts of coke.
