The TOS crew is now sci-fi James Bonds; the characters are timeless in that they are not connected to any one actor (though we'll always have our Sean Connery/favorites).
So the current ones are the Roger Moores of Star Trek?
That is a powerful, accurate comparison; the Moore Bond--in many ways--was Bond
in name only. The trappings might seem similar, but the defining character, heart and aura which made the character an international popular cultural legend (thank you, Mr. Connery), was nowhere to be found in the Moore films--and for every sound reason.
The Moore films continued, but at the end of it all (
A View to A Kill), no one thought the Moore run came close to the power of the Connery performance and films.
