Nemesis was the worst Trek film, no doubt about it. TFF was cheesy And was crappy but at least it wasn't blasphemous. Nemesis was a slap in the face to anyone with an understanding of what TNG was really about.
As a huge fan of STNG and defender of what it is "about", STNG NEM was wholly in line with STNG on tv. Picard tried to believe Shinzon's peace overture, and even tried to convince him twice to convert to the younger Picard's point view (the Picard who became a mature Starfleet officer and explorer). He appealed to his wonder, which Picard knew he shared, but to no effect. In the end, the Romulan's lust for power evolved into realization of genocide, and they turned against Shinzon. Even the space battle, which STNG had few of, demonstrated two enemies could cooperate together. One of my favorite parts of the movie was the very end, when Donatra suggested peace might be the way for the Romulans and Federation. That is VERY STNG in my opinion, and far less trite than Shatner's "god is in all of us" BS at the end of STV.
You want "blasphemous"? How about Spock having an emotional younger brother, or Uhura turning into a stripper, or three of the most respected fictional characters in TV history getting drunk at a campfire, or SPock letting his captain be captured instead of shooting his brother, or Sulu and Chekov getting lost, or Scotty banging his head on a beam....need I go on??
