I really never liked Robin Williams, RIP. I thought he was talented, but just didn't like his style.
I agree on Neil Patrick Harris. I always thought he was unsuited for the roll in "How I met your mother". He was good one year when he hosted one of the awards shows, like the opening number was good. Other than that, I am not a fan.
Honestly, I don't watch enough movies or television to comment on this thread, but I did anyway.
