You know i have a feeling that if a clone of the young Nimoy as seen below was cast in the place of Quinto, there would be lots of whining about how he looks wrong for the part and not much like the serious, dignified with authoritative voice Spock we know.
I think Leonard Nimoy looks a lot like Leonard Nimoy, thank you very much.
Furthermore, both Shattner and Nimoy, regardless of what you may think of their acting ability, are very unique individuals with a lot of character, something that in my view greatly benefited their roles of Kirk and Spock. All I'm trying to say is that neither Quinto nor Pine strike me as being very distinct or interesting and I'm concerned they will come across as bland. As Quinto has done in the two roles I have seen him play up till now (Adam on 24 and a few episodes of Saylar on Heroes). Totally forgettable. Of course, one could blame this on the matrial he had to do, but how far can this rationlisation go?
I couldn't have said it any better myself, Jefferies.
