Its no secret that Star Trek Nemesis tried to be the TNG version of the Wrath of Khan, but ultimately failed to do so.
I think its interesting to see why this is so:
1. Khan was a villain from the TOS tv series, he had an established history with Kirk, Shinzon was just some villain that came out of nowhere and had no real established history with Picard.
2. Khan's motives for hating Kirk were very clear, while Shinzon's motives were very vague and convoluted.
3. TNG already had its own Wrath of Khan, its called First Contact. The difference between Wrath of Khan and First contact is the roles were reversed, with the hero hating the villain and that obsession nearly destroying the hero. In Wrath of Khan, Khan was Captain Ahab, in First Contact Picard is Captain Ahab. Picard showed far more raw emotion in First contact, where his hatred of the Borg seemed overpowering, in Nemesis you didn't see that, Picard seemed annoyed in that picture. The Borg are Picard's nemesis, not some stock action movie villain like Shinzon. Its the Borg that truly hurt Picard, not Shinzon. Again the Borg were from the TNG show and had an established history with Picard, not Shinzon.
