Warp drive is only one example. IMO, there are many other things that are too different for it simply to be written off as due to a brief never seen since encounter with the Narada.
Which is why I said...
Which is fair enough considering Into Darkness
. But I'm happy with the explanation offered by the writers.
has never been all that internally consistent, even within various series. Why should I hold J.J. Abrams to a standard I never held Gene Roddenberry or Rick Berman to?
But since your going to hold Abrams to one anyway...
It was more than one brief encounter with the Narada
* In 2233, Starfleet loses the U.S.S. Kelvin. There are survivors and certainly sensor logs of the incident.
* In 2258, the Klingons lose 47 starships to the Narada. The same year Starfleet loses seven starships and the planet Vulcan to the same vessel.
Plus, we simply don't know if there were any other incidents in the intervening twenty-five years.
