I think I'm going to have to disagree with you on this one... it touched on concepts of loss and acceptance, but it wasn't very "meta"... there was no greater takeaway from Generations IMO...
You had Soran who couldn't get over the loss of his family and was hell-bent on doing anything to rejoin them, but there was no redemption there... no "lesson learned".
The parallel theme of Picard losing his brother an nephew was supposed to be the counter point to Soran, but again, you didn't ever see Picard go down that same path only to realize just before it cost him everything how wrong that path was... there was no destructive path, no grieving, just a sudden acceptance.
As for Kirk, he was kind of shoehorned in this movie... there was no acceptance that "Commanding a starship is [his] first, best, destiny. Anything else is a waste of material." or coming to terms that it was time for him to allow the "next generation" to take over this path... he was just a convenient plot point.
