If you haven’t caught this from my dialogue yet, I’m sure you will by the end of this review. Let me spell it out for you: Blomkamp tends to repeat himself.
How about this as an example; Elysium is just District 9 with a different wrapping. Really think about it for a second.
Wikus and Max have a considerable amount in common. Max has an accident on the job that leaves him with a short amount of time to live. Ultimately, he ends up sacrificing himself for the better good.
On the other hand, Wikus has – what else? – an accident on the job that leaves him with a short amount of time before his transformation into a “Prawn” is complete. Ultimately, he doesn’t die (his ultimate destiny remains a mystery), but he does end up fighting on behalf of the aliens, sacrificing his ability to live normally on earth, at least for 3 years.
And, for some reason, the viewer is supposed to be sympathetic towards the aliens. That reason is never fully explained, and for me, it’s a bit of a leap in logic. You could say that they were treated unusually cruelly, and that they were forced into a situation they didn’t want to be in, but that still doesn’t make them inherently good, either. The alien race is clearly capable of wreaking havoc, and could probably do a fair amount of damage to the human race if they were so inclined. Moreover, they’re just taking up space and causing more trouble on planet earth.
Those were just some of my thoughts, and maybe you have your own, but I didn’t feel that there was enough of a setup for the viewer to want to care that much for the destiny of the aliens.
