Agreed the clone thing was just dumb. Could still be a part human. Maybe Sela's son. But I was thinking trying to make a small tweak so the ending would not have been so predictable. We saw it coming a mile away. And I went into the movie not knowing that part. I knew there would be a lone of Picard as the villian. And it involves Romulans and Remans, but that is it.
The problem is that the story and the impact of the film would not have worked that way. It was not about Romulans, Remans etc. It was about personality. What makes us human, what makes us unique, where your place in this world is.
The political setup was just the stage for the central play.
I liked it, though I wish they would restore those 50 minutes of footage and make a proper extended cut. It would be the swan song the TNG crew deserves.
