Overrated, but an entertaining one-time watch

Rating: 6/10 (6 January 2016)

I'll skip the plot this time and just summarize the pros and cons:
Pros:
Great seamless special effects. They're done so naturally and shown so offhandedly, that they really look & feel like part of the mockumentary in the beginning of the movie.
A good imagination with the aliens, weapons, ships and technology.
Several entertaining scenes, with lots of humor and action (except that the blend of these different approaches don't work well with each other - see below).
Cons:
The movie can't make up its mind about its approach and type of entertainment. First it's a really silly mockumentary that revels in awkward Office-like humor (which also happens to be a genre I don't enjoy) with a dumb bureaucrat trying to handle the moving of very wild aliens. Then there's the more serious sci-fi elements and drama that clashes with the silly approach. Then there's action-scenes for a shoot-em-up ending.
The aliens never make sense. They have superior weaponry but allow themselves to be subdued with only a few violent fits, they are extremely dumb, except for one fellow for no particular reason. It's like dogs suddenly invented space travel and weapons - it never makes sense.
The movie wants to draw parallels with apartheid and whatnot, but the aliens are so violent, animalistic and disrespectful in their behaviour, it's impossible to sympathize with them.
Character development is a mess: We get a bureaucrat who gleefully 'pops' baby aliens, then he is forced to live with them when he starts mutating but still stays a bureaucratic jerk, and he only helps them when he realizes he needs them to save his own skin, killing his own brainlessly violent co-workers for selfish reasons. Not exactly satisfying. And yet it seems the movie wants us to sympathize.
Given the above, and the fact that the police also are so cartoonishly fascist and violent, there is no side to take with this movie and nobody that is likable.
Therefore, this is a one-time watch only.
