What was a retread ?
Well, let's see ...
A man named Khan, frozen for centuries, being one of the lead characters.
A problem with the power system, requiring someone to enter an irradiated area to die to save the ship.
The person who dies of radiation is returned to life (this time in the same movie).
A blond named Carol Marcus.
(were there some more?)
By that standard, pretty much all of Star Trek
has been a retread to one degree or another since Where No Man...
