THe first black hole could have been affected by the star in some way, causing a tunnel through time. We don't relly know, but it was in a significantly different situation to the others, so that could be an explanation for the different results.
As for the remaining two black holes, the one at Vulcan was created using one speck of red matter. The one at the end was created with every drop of red matter that Spock had. Ergo, much bigger and more dangerous black hole. I don't think that one is too hard to make sense of.
I do agree about ejecting the core, though. The Enterprise really should have sunk back in the moment they ejected, being that it was taking maximum warp to hold them steady. You'd also not expect an explosions to blow outward when it was that close to a black hole. Should have been sucked in.
The big question I had though, is what happened to all those black holes they made? There's now some super-massive black hole a few warp-seconRAB from Earth. That can't be good!
Nero did say he was going to save the Empire, but he was also going to give it a future free of the Federation. Considering he'd just destroyed 47 Klingon ships and then kicked the arses of a dozen more Federation ships, it seems pretty clear he outgunned the competition immensely. He probably couldn't see any risk to himself and so wasn't concerned about possibly being killed during his revenge mission.
That's part of the point of the film; he completely outgunned the entire Federation, but he didn't bank on James T. Kirk. Once again, Kirk beats all the odRAB.
Its not that stupid, really. Kirk was a liability in the middle of a major crisis (in Spock's mind), so getting him off the ship isn't that stupid an idea. He did dump him on a planet with a Starfleet base on it and if Kirk had remained in his pod - as instructed - he wouldn't have been in any danger. They could have locked him in the brig - but as a Star Trek fan, you must already know how useless they are at keeping prisoners secure!
As for landing so close to Spock, personally I don't need an explanation for that. There have been many good ideas put forward for this - but quite simply, this is the sort of convenient plot progression technique that is quite the norm. You could find then to the penny in every Trek series if you want to look for them.
I just don't find that level of nitpicking necessary.
THIS one I agree with. It was daft to see Vulcan so large in the sky of Delta Vega. If it were that close, Delta Vega would have been sucked up into the black hole, too. Heck, if it were that close, the two planets would probably have collided due to their own gravity, millenia ago.
They could just have given Spock a telescope to watch through and done away with a rather silly looking special effect.
I'm gonna agree with this too - although it didn't bother me too much. IT just seemed like they'd left themselves stuck without a way to get Kirk back tot he Enterprise, so invented some technobabble to get him back. It was Voyager's biggest crime (aside for the shit stories and lame characters)
The fact that they couldn't transport like this even in TNG's time also made it seem out of place. Not because they were breaking with continuity (let's face it, ALL of Trek has broken with its own continuity at some point) but because they were trying to make out like they were following continuity and they weren't.
This is where you lose me completely. I just can't be doing with "the insignias weren't right" or "ther enginie room looked wrong." The engine room in TOS was a box and in TMP it was a cathedral-like massive room with a pillar for a warp core.
The Enteprrise was was made of cardboard, plywood and christmas lights in TOS. It looked like a completely different ship (ie. one that ight actually fly) come the movies. They made the Enterprise's insignia the logo for all of Starfleet because they realised all the other ones looked wank.
As Bones would say - good god man! Star Trek is littered full of these sorts of cosmetic inconsistencies. Data had the wrong rank on in "All good Things..." when it flashed back to "Encounter at Farpoint." The Enterprise fired phasers out its torpedo launcher in "Darmok." The background crew in TNG walked around in the season 1-2 uniforms for years after the main cast got a new wardrobe. Get over it, already! If fans REALLY cared about these kinRAB of details, they'd have hated ALL of previous Star Trek!
Aside from Uhura speaking Romulan, where you are totally wrong and even continuity is against you. The first Romulan War involved no visible contact with the Romulans, but a peace accord - which resulted in the famous Treaty of Algeron - was negotiated via sub-space radio. Therefore, it is quite clear Starfleet would have had ample record of the Romulan language.
That and we saw Hoshi translating an intercepted ROmulan message in Enterprise, too.
The acting for the most part was good. Adam from 24 was good, Kirk was an utter **** but he was written that way. I found Scotty funny (the Willy Wonka Super-Ride-O-Tube bit was hardly his fault) and Bones was spot on but he was sidelined a bit because old-fashioned country doctors don't sell as many tickets to teenage boys as girls in their underwear do. Uhura... why did they change her character so much? Was that scene in the bedroom really necessary? And if someone's mother dies right in front of their eyes, and indeed most of his entire species, is it really appropriate to lock him in the turbolift and try and get in his pants? Besides, aren't there laws in Starfleet about banging your students? You can imagine Kirk getting away with something like that but Spock? It's illogical. Besides, I thought that Spock always loved Kirk, unless weird internet porn and deranged fan stories have been lying to me all these years.
So, nyah, nyah, nyah. I out-geeked you there
Star Trek's always been all-over-the-place when it comes to time travel and multiple universes. Just like all the points I made before, Trek;s continuity is pretty shite really. It's so all over the place, its best not to worry about something as minor as this.
Why is it minor? Because we only have Spock and Uhura's word that this is now a parallel universe (doesn't matter what the director/writers say off-screen because that's not canon) so for all we know, it may really have wiped out all prior history and reset the timeline.
You do realise that the ONLY reason the "alternate universe" line is used is to appease the crazy fans who would have gone into cardiac arrest had they actually said they'd wiped out 40 years of continuity. Heck, enough fans are complaining of that anyway - without it being said - so imagine how much they'd be whining if it was said on-screen!
