was the first Trek movie I had ever seen in theaters (I have been a Trek fan since the early 80s but one reason or another kept me from ever seeing them in theaters).
In theaters, it was enjoyable, all of the questions I had were pushed to the background so I could just enjoy the moment. I don't know if that would have worked had I seen Insurrection
in theaters prior to that outing.
When my friends and I went and saw Nemesis
opening night, there were, maybe, 5 other people in the theater with us. The movie complex itself was packed, but our theater was all quiet and nearly empty. Based on that (entirely anecdotal I know), I'd say Insurrection
mortally wounded it, and Nemesis
made the killing blow.
Now, that doesn't mean I hate those movies, but they did seem to contribute somewhat to the end of the TNG franchise's popularity in movies.
