It's as if they're pretending to not know there was an obvious age difference between the two actors from Star Trek/ Shatner in his 30's and STC/Vic in his 50's. Brian Gross who played Kirk was more age appropriate and made the character his own, not trying to ape William Shatner.I don;t think one has to have a "hard-on against" a show to personally feel someone was miscast in a role.
I have no problem with the same actor, Jim Johnson, portraying the same role he created years later.
