Simple start to this review, this is film is complete rubbish. Here's why:
Terrible pacing.
Showing people doing nothing with no purpose, not moving the plot forwards or developing the story or characters is boring, simple as that. The whole first 40 mins could be removed, and no one would notice.
Terrible characters.
Spending time with Em, would be like spending the weekend using a pair of cheese graters as headphones. What an annoying character she was. The male chap, a man that looked like a constipated person on suicide watch, who had listened to too many Morrissey records. He was about as interesting as listening to an 8-hour insurance seminar.
The Plot.
The main characters motivation is to get some money, well, so why spend a fortune on camera equipment? Does anyone believe a photo of an alien craft (as they thought it was) would make money, there are plenty on the internet.
Lack of logic/Believability.
For some reason this creature for the most part hides in a cloud and picks off a couple of horses, not to raise any suspicion. By the end of the film, it is zooming around in clear daylight, not giving a jot about being seen.
Don't Knows (you must imagine the "don't know" is said in a sarcastic drawn-out way).
How did it get there, how long has it been there, can it reproduce.... Don't know.
It only affects electrical devices as it flies over them, okay so film it from a far, with a zoom lens, problem solved, why don't they do this? Don't know.
At one point it turns into a cross between a camp lampshade and a tissue paper exhibition, why, for what reason.... Don't know.
It decides to throw up/relieve itself on a small house in the middle of nowhere, why... Don't know.
It doesn't attack people if they don't look at it, wouldn't that make it very easy to deal with then? Why did it attack the man with the silver helmet then.... Don't know.
Why would Jupe have a "show" to meet the aliens, how did he know about them, why didn't he mention it to anyone, didn't he think about the potential danger.... Don't know.
Why does the creature hang around the place with the least amount of its food source.... Don't know.
I could go on an on. What is shocking, are the arrogant pretentious reviews, "you didn't get it". I go to see a movie to be entertained/surprised/moved/informed. I don't go to see a movie to be boring, silly, and empty, but is really meant to be symbolic/allegorical/existential, so therefore I should review it as brilliant, even if it sends most people to sleep.
We can all pretend any poor film was meant to be mean this that and the other, it was badly made crap, stop trying to make excuses.
What's next, Plan 9 From Outer Space, was genius representing the struggle of communism against the West.
