Not all the appealing mascots of today are as appealing as yesterday. Correct me if I'm wrong but isn't this the late Yul Brynner from the King and I? To say that the original is always the best is an overstatement. He does look like Lex Luthor here and not very appealing for an advertisement.
The current Mr. Clean looks more appealing and friendly. So who says original is always the best? Besides, a lot of company mascots needed to be revamped so they look more appealing to the public. Otherwise, it's just bad publicity.
