Attractive characters improve games. True or false?

[Tober]

The playable character needs to be appealing in some way or another.

Pretty, handsome, sexy, cool, funny, adoring. A positive reaction is needed. If a character is unappealing in any way being bland, ugly or annoying, I will not be interested in playing the game.

Now what is appealing is subjective to an extend. Mostly game designers get it right to appeal to my taste. But certainly there are also times they got it very wrong and in these times I don't care how good gameplay might be, I still don't want to play the game.
