For the same reason that I wouldn't get overly excited about a new series about the Borg because we've already been there in Voyager or the Dominion in Deep Space Nine. The Klingon vs The Federation thing has already been done within the original series, DS9 season 4, TNG "Yesterday's Enterprise", "All Good Things", among other places. Hopefully the series won't focus on that. Does anyone else feel the same way? why or why not?
