I honestly try to come up with positive things to say about the movie - But even the core concept wasn't any good, as I can say about Ent or Voy. The actual original idea sucked and the movie was pretty much doomed from then on.
Picard's mid-life crisis - Not only was this a rehash of The Wrath of Kahn with Kirk feeling old, it's already been done for Picard too - 'time is the fire in which we burn' ring any bells?
B4 - Been done, both the concept of a second Data ('Datalore', 'Brothers' etc) and the 'finding mysterious data parts' ('Times Arrow'). Plus the character was annoying as hell and just a way to completely undo the only significant event in the film:
The Death of Data, which in itself was just more 'TWOK' rehashing. The non-human character takes on a suicide mission to save his crippled ship from the villain's (who has a personal vendetta against the captain) superweapon. Before he dies he has a chance to say a last goodbye to his captain.
Shinzon - An attempt to rehash Khan, with a brain-numbingly nonsensical backstory, and only the barest resemblance to Patrick Stewart.
I could go on.
The only good idea in the film was the whole Romulan/Reman thing and that never passed a paragraph of exposition in terms of depth. I'm truly sorry to derail your positive attitude, but more so than anything else in the franchise I find it very hard to find any redeeming features in this film.
