Kirk I've never been a fan of, finding him to be a jerk most of the time. NuKirk is much the same, though he is definately better looking.
NuSpock is alright.
NuScotty just doesn't feel right. He seems too angry and bitter about life.
NuMcCoy I like, though given the paradigm shift in the NuTrek focus we haven't seen nearly enough of him.
NuSulu hasn't really done much so far.
NuUhura is grating, snide and unpleasant.
NuChekov again hasn't done much.
