It's absolutely
terrible. I resent the fact that so many people took the bait and think it's "deep" simply because it references apartheid.
I resent that people accept movies where we don't understand the characters' motivations; or the motivations change without reason. It's clear that whoever wrote the screenplay just kept writing on and on without stopping to fix/rewrite the parts that didn't make sense. If the writer doesn't care about the story and the characters, why should the viewer care? The attitude that "it's OK because it's just a movie" leads to crap like the
Transformers movies. Fffffffffuuuuuuu------.
It took Christopher Johnson (the bigger alien) and the little alien over 20 years to collect enough alien fuel from the slum debris to fly the dropship up to the mothership. They emphasized that the very last droplet they collected was absolutely 100% necessary.
So what were they going to do when they got to the mothership? Before they left the mothership, it was stranded on Earth for some technical reason. Were CJ and the little guy going to solve the technical problems
by themselves and fly off? If so, why did they ever leave the mothership in the first place? The aliens that emerged from the ship were emaciated and starving, so we know that provisions were completely exhausted. They stopped at Earth in desperation. I don't know how they planned to return to their home world alive.
So Wikus finds the canister of collected fuel. He doesn't know what it is and accidentally sprays himself with it. Hundreds of droplets are wasted. That means they don't have enough fuel to get the dropship back to the mothership...right? I guess not.
Is it actually fuel? I guess not. It inexplicably starts turning Wikus into an alien. Even though Wikus was sprayed in the face, one of his arms turns into an alien arm before any other body part. So, awesome alien fuel does
that? OK. Makes sense.
MNU scientists are fascinated by Wikus' arm. They think it might allow other humans to use the alien weapons that won't fire with human hands. For this reason, Wikus is extremely valuable to them. Then they inexplicably decide he's not valuable at all. They plan to chop off his arm and let him die. If they were going to do that, why can't they just chop the arm from any one of the aliens? Clearly they consider the alien lives to be disposable or nearly worthless. They killed several of them while testing the alien weapons.
OK. So Wikus escapes (and they're definitely trying to kill him). CJ thinks he can turn Wikus back into a human. I don't recall if CJ needed Wikus for anything at this point. After escaping the MNU lab, CJ should have parted ways with Wikus forever.
Armed MNU operatives are approaching the shack where Wikus and CJ are hiding. They're working frantically to start the dropship, which is buried beneath the shack. Wikus desperately wants to reverse the gradual transformation and become 100% human again. CJ is the only one that has even hinted that there's any possibility of this. CJ generously offered to fix Wikus when they escape the planet and get to the mothership. While working to activate the craft, CJ reveals that it may actually take a few years to fix Wikus. CJ will probably have to go to his home world first. Wikus flips out and...and...knocks-out CJ. I repeat: CJ is Wikus' only hope of ever being human again. Instead of dragging CJ into the hidden dropship below the shack, Wikus deliberately leaves CJ for MNU to find (and they usually don't hesitate to kill the aliens). Wikus has absolutely no idea how the dropship works or what he'll do when he gets to the mothership. Luckily, his alien hand allows him to pilot the ship with his mind when he dips it into the goo.
The dropship gets shot down by missiles. Wikus has to flee the ship on foot. Wikus encounters the maniac gang leader / warlord that wants to eat Wikus' alien arm -- believing incorrectly that eating alien body parts might give him the ability to fire alien weapons (though it hasn't worked with any of the aliens he has eaten before). While the gang members hold Wikus down so the leader can eat the arm, Wikus manages to get his hand on an alien weapon. He kills everyone in the room (even women)...
except the gang leader!? The leader is threatening him. Paraphrasing: "I am unrelenting. I am not intimidated. I will catch you. I will kill you. I will eat that arm." With the alien weapon, Wikus is in a position to quickly and easily solve that problem. He didn't have any issue with killing the gang leader's underlings. So Wikus shoots the leader, right? No. Does the gang leader show up and cause a problem later? Absolutely.
This part is just bad filmmaking: Wikus is taking cover from heavy MNU fire that's directed at him. He's right next to a heavily-armored alien mech / walker thing. The movie cuts back and forth between the fighters outside and Wikus inside. We know he's going to get into the armor, but he doesn't. The movie cuts back and forth a few more times. It's unbearably tedious. When he finally gets in the armor, we see that it's exactly as we expected: It's nearly invincible for a period of time. Why did they waste all that time not advancing the story at all?
For some inexplicable reason, Wikus starts fighting his way back to the dropship that was
shot down earlier (when he had been piloting it). Why does he think it will fly again?
Before he goes back to the downed dropship, we have to endure more excruciating bad filmmaking. It has been shown that this armored walker mech thing can withstand a lot of heavy firepower. He sees an opportunity to try to rescue CJ from MNU guys that are about to kill him. For no conceivable reason,
Wikus delays and acts conflicted about whether-or-not he should save CJ.
Wikus,
- What are you going to do when you get to the dropship that was shot down?
- What are you going to do when you get to the alien mothership?
- Do you remember that CJ is the only one that even hinted it's possible to make you 100% human again?
- Do you remember that CJ generously offered to do it even though you have nothing to offer him?
- Do you remember that you are the reason CJ was captured in the first place?
Supposedly, the answer is: "Wikus is stupid and impulsive." That doesn't make any sense at all. It seems that his "impulse" is to die and sabotage everything for no reason whatsoever.
Alright. Then they activate a tractor beam to bring the dropship up to the mothership (so the fuel was
completely unnecessary). For decades, the dropship had been buried directly beneath the mothership it had been dislodged from. So why didn't they activate the tractor beam in the first place?
I still don't understand why the aliens even left the mothership 20+ years earlier. Why is the mothership suddenly able to leave the planet? Apparently, it's still capable of bringing CJ and his son back to their home world.
