I think it was a mistake to tone Chen down, She's the only new character with a distinct personality on the E-E. They killed off the others (Choudury, Leybenzon). The current ones, Smrhova, Faur, Elfiki, Konya even Taurik have little to set them apart from the crowd. I would have loved to have seen more of that female Klingon conn officer lonemagpie introduced in Indistinguishable from Magic (Kat?) or a character ported over from New Frontier. I could read a whole novel about just a session for captain Picard with Hugh Cambridge.
