Re: "Enterprise I'd rather forget."
There was the end of series^H^H^H^H^H^Hseason finale where they'd saved the Earth from the Xindi, but to have a cliff hanger into the next series they suddenly went back in time (can't remember why) to when aliens were posing as Nazis (I don't /think/ I'm making this up, or am I getting confused with Galactica 80s?). Anyway, there was a definite "going back in time" CGI effect after which I fully expected Captain Archer to say "Oh boy!" (he didn't).
