I do wonder what's worse of the fandom:
An actor/actress that looks like the source material completely, but gets the character wrong. (Raimi's Gwen Stacy was an utter waste for such an important character in Spider-Man lore, for example.)
An actor/actress that doesn't look like the source material, but nails the character. (
This in not precluding getting both right. This is wondering which is worse on a personal.
It's interesting, because we have a long history of characters that don't have the look or the temperament of their comic counterparts, that people have largely been fine with. As an example, either Flash, television or film. Neither is Barry Allen really, in look or character.
