At the risk of getting dragged into a TNG argument, and
Nemesis being the only Next Generation movie I refused to see in the theaters, isn't there a link in to that stupid plot line involving the alternate universe Tasha Yar? I hate to admit this, but I don't know why they bothered bringing her back in Season 4 (or was it Season 5). Never cared for her or her character, and thought it was a dumb thing to do based on that episode.
TNG was at its very best when dealing with the Klingon civil war - those episodes were just cool in so many ways. It looked like DS9 was going along those lines the last 2 seasons with the Dominion Wars, unfortunately, we got really busy with kids sports for those years, and couldn't follow them - now nobody local is doing them in sequence.
No, but there's plenty of other stuff just as stupid.
