I was so young when this show aired that I did not understand what he was really doing. I may not have continued watching when the Preston was replaced; I have no memory of that. Preston must have been effective in the role--he held my interest. I do recall that the mustache was a bit of a turnoff for me. Yeh, I wanted my 19th century heroes to look like mainstream 20th century men. But I kept watching. I recall comic books, too.
