Not enough bashing in this thread so here goes:
1. How does a supernova threaten the galaxy? Bad science and/or poor explanation as to why in this case it should.
2. Black holes are not gateways to the past. While there are such theoretical postulates as Einstein-Rosen bridges or more commonly wormholes, there is no particularly reason to believe passing through the event horizon of the singularities in this movie would do anything but crush the hell out of anything that found its way into it. Frankly, I think the authors were afraid to get too technobabbly and offer something up more like a spatial-temporal rift as found in "Yesterday's Enterprise".
3. If one drop of the red matter created such a powerful singularity, what the hell happens when a giant ball of the stuff does what it does? Shouldn't there have been some insane super-giant black hole created right smack dab in the middle of our own solar system??? Way to go, guys, you just screwed the whole Federation. Plot hole you could drive a truck through.
4. The red matter is frigging JJ Abrams' frigging floating red ball thing that was seen in Alias in another form. Recycled much? And what the hell kind of name is red matter? Are we too stupid to have it called super-duper graviton particles or some such?? Again, avoiding the technobabble.
5. Why the hell did they have to destroy Romulus and pretty much the whole Romulan empire? Isn't this pretty much the same crap they pulled in Star Trek VI with the destruction of Praxis essentially spelling the end of the Klingon Empire? Doesn't anything bad ever happen the Federation? Biased much??
6. Why does the inside of the Enterprise look like a factory and not a space ship??? Because it is a frigging factory!!!! That's the set they used for interior shots of engineering levels!!!! You'd think with all the money spent that they could have at least gave us some sets that looks like they are the interior of a faster than light ship.
7. Why does the bridge look so much damn different than every other part of the ship that we see? You've got this crazy bubble-gum machine, IPod bridge and the rest of the ship looks like an industrial park??!! Doesn't make a lot of sense to me.
8. What is up with that Romulan ship?? It looks like some black frozen space squid corpse!! When I see a Romulan ship, it better look like a frigging bird!! It can look like an insane bad-ass bird, but it needs to look like a bird, not a spiky space turd.
9. What's up with that frigging Romulan ship?? Yes, I design all my mining ships with vast empty dark spaces and randomly placed platforms that are conveniently easy to jump to in some movie climactic fight!!! Most ridiculous ship interior ever. Again, so much money spent on this film, where are the amazing sets for all that dough??
10. What is up with that Romulan ship?? Yes, I like to have open pools of standing water covering the deck around all sorts of electrical equipment, and I like to stand in them while interrogating prisoners in my prison interrogation chair that I have on my mining ship. Save the drama for your mama. Do something, show something that makes sense. Silly, silly overdramatic nonsense.
11. Apparently, the only mathematical training the Vulcan children receive revolves around the area, volume and/or the circumference of a circle/sphere. Do they really think we are that dumb or are they trying to make us feel smart or something by placing these recognizable equations in those scenes? Is that the extent of the writers' mathematical knowledge?? Geometry/Trig??? Weak sauce.
12. Could Zachary Quinto looked more uncomfortable kissing a woman? When Spock kissed a chick in TOS, she got kissed. That was some weak, weak romance in those scenes. Zoe Saldana was good in those scenes but my god was Quinto seemingly out of his depth. I didn't mind the relationship but its execution in the movie was poor.
13. Could Kirk's troubled bad-boy to superhero transition be more cliched? Is this Top Gun/Good Will Hunting?
14. Why, oh why, is there a finale scene at the beginning of this movie? The first 5 to 10 minutes of this movie are practically the best scenes in the movie. The Kelvin, George Kirk's sacrifice, etc. Frankly, I spent all my emotional energy in those beginning moments of the film. After that, it was pretty much just the roller coaster ride. A weird choice that left me with very little energy to actually care about any of the characters.
That's all I got for now. More to come later.
