Nu-Kirk seems to be Gary Mitchell impersonating Kirk. Nu-Spock seems like a cross-dressed Saavik. Nu-McCoy goes back and forth between caricaturing McCoy and getting it spot-on.
The nu portrayals of Sulu, Scotty, and Uhura seem to be based on the character descriptions from TOS, disregarding the performances. Nu-Chekov appears to have tried to fix TOS' problem with not knowing what to do with him - is he the Monkee, the braggart Russian, the young supergenius, or the screaming idiot?
Nu-Sarek had no gravitas. We barely met Amanda's counterpart: "Oh, cool, Winona Ryder - oops, she's dead"
Nu-Pike was a major departure, but then there wasn't much to go on.
