A total artistic wank piece. The plot moves at a glacial speed, thanks to all the filler in it. Sure, it's about a curious alien living among humans and consuming them in some mysterious black fluid that only said alien can walk on.
Other than that, it is absolutely boring as hell and totally lacking in any amount of entertainment. The cinematography itself is great though only in some limited moments. I have a thing for beautiful landscapes but let's be realistic, I watch National Geographic and BBC documentaries for that. Otherwise, a lengthy look out in thick white fog from within a motor vehicle is not my idea of an entertaining nor intriguing scene.
In short. Absolute rubbish. After the first five minutes, I realised the glacial pace of this film and watched it at 8x playback speed to try and find some semblance of a climax. Nup, nothing.
Don't waste your time. It failed financially and if you dare to still watch it, you will realise why.
