"I saw Todd during the first week of previews. He was average at best. There was no shading to his performance, and he didn't really offer up the outrageousness the part demands."
You realize that you are saying you saw his 4th or 5th public performance, right? It's not like you saw him three months into the run where he has had the time to find shading and outrageousness for the part?
People who judge solely on previews don't really deserve an opinion.
