I like the chance to see the crew after they have returned home. I hated that what we saw in that never happened. The use of time travel by that point was tired, and then, on top of it, to use the Borg as something important to getting them home seemed almost cliche.
In addition, Janeway's motivation didn't make much sense. You're going to follow the Admiral's demands because Chakotay dies after he marries Seven and SHE kicks it? Wait... after all the other crew members you no doubt lost, this is the one? Besides all that, if you were coming back to save the lives of your crew, why not go back to the very start with a way to get them home and destroy the array? That way none of it every happened? I mean, where's the line?
Where are the temporal time cops to keep you from fudging up the timeline? They've been there at least twice before to keep you from doing that.
AND... after waiting SEVEN years to see if they get home, we don't even get to see a brief reunion between the crew and their loved ones? WHAT?!
No, I didn't not care for this ending. They could have done so much more.
