You gotta forget the original, or
Explain it the way that Worf explained the different look of Klingons when they used some clips from the original in a STNG episode:
"It is a period in our history that we don't like to talk about."
I like Enterprise. They are nervous about using the transporter so they use shuttles and you see the occasional space suit. Still some silly plots, the show requires unconditional loyalty. :)
