There's two ways to look at Upside Down (pun intended). On one hand its a movie with terrible story telling and really bad science, yet on the other hand its an incredible achievement of style and fantasy. Being an optimist I've chosen to embrace the positive side of Upside Down and approaching it as a fairytale has given me an exhilarating and mesmerising experience... with one hell of a throbbing mind-fuck! The movie is bookended by a really poorly written narration that explains that the story takes place elsewhere in the Universe where two planets exist beside each other and share a dual gravity. So close are the planets that a corporation connects the two with a tower. Upworld is a privileged society whereas Downworld is impoverished. The two are forbidden to interact outside of the corporation and the movie tells of two lovers from each world who meet at the closet point between the two worlds (mountain peaks within feet of each other). The premise is stupid but the film is so visually incredible that its easy to become enchanted by it. The entire story is presented in a weird and wonderful mirror image and blending it so seamlessly is a masterstroke of cinematography and editing. Adding to the magical aesthetic is a soundtrack featuring Sigur Rós and a conceptual design that'll blow you away. So my advice is to suspend your disbelief and give in to the fantasy. Physicists will either tear their hair out or die from laughter but anyone with a big imagination and sense of wonder will find something tangible about Upside Down. Go on, watch it... you're eyes will thank you.
