More plotholes than a sieve
Is the American populace getting more and more stupid leading to them willing to accept ever increasing stupidity in movies? You decide. Here are some of the glaring plot holes off the top of my head. Feel free to add your own.
1. Aliens travel light years through space but could not avoid a collision with an earth satellite.
2. We are using slower than light communication to communicate to planet G, which is already lightyears away... (Really, I'm pointing out how hollywood loves to show us things that things are transmitting by showing a slow beam of light (visible no less) moving up through the atmosphere.)
3. HK authorities could identify that the crashed ship is a communications ship within hours even though we don't know what it's made out of (Only one element identifiable as stated in the movie) This is like presenting the Aztecs with a doppler radar and having them know what it does.
4. Humans have learned that unguided munitions are kinda bad since 1940s... yet aliens with interplanetary space travel abilities still rely mainly on unguided munitions.
5. Shooting 2 anti-materiel rifle with no ear protection multiple times is no problemo... even though they are regularly louder than 160 dB. 130+dB is the threshold for pain and dB is on a log scale... To me it's like watching a person get shot, but they brush it off like a meth crazed addict with cocaine up their butt.
6. Apparently, shooting .50 cal rounds at alien "windows" would definitely work. Much like how bronze age weaponry would be super effective against the composite armor of today.
7. Drifting the USS Missouri. Need I say more? The inertia would either snap or drag the anchor.
8. Because my pet reptile eyes looks like alien eyes, and my pet hates the sun, the aliens must hate light. Bulletproof logic (Our sun isn't even a luminous star)
9. Aliens have yet to develop nuclear weaponry which would one hit destroy the ships. (Bear in mind that if the aliens wanted to preserve this planet for colonization, nuclear weapons do not have to have radioactive fallout. The only reason it does is because our technology uses fissle-fusion bomb. A pure nuclear fusion reaction would have no fallout. Not to mention antimatter)
10. Aliens can't see us because we're still alive. (as mentioned in the shoehorning battleship board game scene) Bulletproof logic. Why it is that the alien's can't see the John Paul Jones at night is never explained. Why bother closing in on the range to attack the John Paul Jones in the first place? Were they going to ram the ship? If not, why not just shoot the John Paul Jones? I guess they haven't developed night vision, infrared sensors, heat seeking missiles nor a big flashlight yet *roll eyes*
11. Aliens have developed radar cloaking technology. Fine. They're aliens. That prevents the John Paul Jones from using over-the-horizon target tracking and missiles like the Harpoon. This does not prevent the aliens from using their own alien target tracking systems from firing over-the-horizon missiles to shoot the John Paul Jones/other battleships.
12. I guess the alien's haven't developed miniaturization yet. We've gone from house sized 1MB HDD to 128GB in micro SD but the aliens need to bring in dropships to send a simple S.O.S back home. They should've just raided Jeff Goldblum's apple computer.
13. I'm not going to talk about recommissioning the USS Missouri montage cause it's been pointed out a billion times.
