Nitpicking Star Trek First Contact

"Resistance is futile"

-Every Borg ever in every Star Trek series that featured them

So, I know it's by no means a new movie, but I just finished re-watching First Contact (the second Star Trek: The Next Generation movie). I still think it's awesome, clearly the best of the TNG movies, and in contention (with Star Trek 4, naturally) for the best Star Trek movie ever made. However, some niggling things did bother me:

1. The Borg go back in time to assimilate Earth. They choose the time when mankind is about to launch its first warp-capable ship. Now, their goal of assimilation is to "add your biological and technological distinctiveness to our own". So, if they want the technological distinctiveness, don't destroy the warp ship! Let them advance a bit, but then attack them while they're still weak. And if you just want the biological distinctiveness? Go back even further, why cut it so close? This bugged me about Terminator 1 & 2 as well. Fuck killing John Connor or his mother. Go back to colonial times and kill his great-great-great-grandmother or something. No giant steel factories back them to get knocked into, no pneumatic presses to be crushed by. Now, as for First Contact, if your goal is to incorporate biological diversity in the hopes of creating a perfect species, and you have access to fucking time travel, just go back in time until every species was in its caveman days and incorporate all the biodiversity you want with no resistance whatsoever. You may not get the tech, but who cares? You'll have nobody to fight and thus won't need the high tech anyway.
2. Deanna Troi finds Zephram Cochrane and gets pissed with him on Tequila. Used to synthehol, this intoxication is understandable. She passes out on the table stone cold wasted. But then half an hour later she's up and about and sober, talking about the future? What the hell?
3. Here's another thing that bugs me about Sci-Fi, as much as I love it. If human beings aren't alone in the galaxy, we're probably not really that unique. So it's just hubris to think that we are. Every species the Borg encounters, they assimilate en masse. But they meet humans, and what do they do? They turn Picard into Locutus of Borg, make him an equal to the Borg Queen/Hive Mind. What the hell makes us so special, and so much better than the Romulans, Klingons etc. that we're seemingly the only species where one of our cohort gets to retain individuality-gets a name, a special positions etc.-in a society that embodies hive mind conformity. That's just hubris on the part of the writers.
4. The Borg take over the majority of the Enterprise. To kill them, Data ruptures the primary warp core plasma conduit, destroying the organic part of the Borg Queen. Yet, within half a day, they manage to hide the entire 24th-century Federation flagship from the Vulcan vessel that notices a tiny warp signature from Cochrane's rocket, and then facilitate all the repairs necessary to get the hell out of there (including reproducing the Borg's time travel to get them back to the 24th century), within a few hours? I don't buy it! The Borg had totally interfaced with the Enterprise's circuitry and taken over all of engineering and over half of the rest of the ship, the deflector dish had been shot into space, and the warp core's plasma conduits had been cracked open by Data's mighty fists of fury. And all that only takes a day to undo, despite like 75% of the crew having been killed/assimilated by the Borg?
5. Hey guys, here's an idea: let's not waste some of the coolest high tech we've ever seen! Picard, I'm sure it was very cathartic to break the Borg Queen's metallic spine. But you know what would've been more cathartic? Studying it, so when you encounter the Borg again, you know how they operate. And you obviously figured out a way to travel through time, in order to get home; do you not think that might be knowledge people would want in the future? In Star Trek 4, they could only travel through time by getting a tiny Klingon Bird of Prey and whipping around a star's gravitational field (or something like that). You just found a way to move a 700m-long ship through time to a precise temporal destination. That seems like knowledge you might want to share, yet never again do we see time travel in any future movies.

Anyway, I know this was a nerdy and silly rant, full of pedantry, but still, these things irked me. I am happy to give lots of suspension of disbelief to futuristic sci-fi, but this was just silly and seems like sloppy/lazy script writing. The movie was still great, but why make such minor elements so improbable?

"Brave words. I've heard them before, from thousands of species across thousands of worlds, since long before you were created. But, now they are all Borg."
