Then you aren't entitled to "your opinion" in this case.
You haven't seen him in the role. How can you have an opinion without seeing him? What you are doing is making a blind judgment based on your preconceived notions of a performer.
And if you truly wanted to have a discussion you would have started the thread differently. You started this thread to stir up **** and now that nobody is agreeing with you, you're backpedaling.
Here's how a thread wanting opinions would start:
Has anyone seen him in the role? What do you think.
Or even if you're skeptical of him being good, it could have been more gently put.
How is Harvey in the role? I just can't see him as Tevye. What do you all think?
