Captain Robert April said:
If I was in charge of the preproduction of "Enterprise", I would've kicked things off with a staff meeting with the art department and the costume designers, put up a slide of a still from "The Cage" and told everyone, in no uncertain terms, that they were to forget about alluding to TNG, DS9, Voyager, the movies, even TOS, and, pointing to the picture, "THAT, boys and girls, is what we're supposed to be leading up to!"
The other shows already progressed naturally from that point onward, so all Enterprise had to worry about was be a logical predecessor to "The Cage"; the rest of the franchise would take care of itself. Instead, what we got was a prequel to TNG, with occasional allusions to TOS, and in that respect, Enterprise was an utter failure.
