I watched the film Upside Down recently and, god, it couldn't have been written worse if the responsibility had been left to the drunken ramblings of a troupe of peyote-drinking retarded chimpanzees mashing their mutilated stumps for hands against a typewriter where the only keys that worked were s, u, c and k.
This film follows the romantic formula to a tee, except it does everything in its ability to be even less intelligible by discrediting science in the process. The story's premise destroys the basis of physics to such an incredible degree that even a five-year old would state that this film makes no sense and would not have a shadow of a doubt that he was correct in his assessment.
So, the premise is that you have two planets that are perfectly aligned (they spin at the same speed, with the exact same orbit and I would surmise the same mass, considering they're not smashing into each other) such that there is a bridge that transitions between the two of them. So far, so unrealistic. Now here comes the kicker; the gravity doesn't work the same between planets. Oof. Items from the one planet only interact with the gravity of their planet. Ouch. If these foreign elements are retained too long on the other planet, they burn up. Owowowow. Also this gravity apparently only affects certain aspects at certain times (or at least the way that this film conveys it). All this 'science' is introduced so that we can have the world's most convoluted romance story possible: (narrator voice)
Two people, living in separate worlds ... but connected by love
I'm not sure why they needed to go to such silly extents to create such a convoluted mechanism to keep them apart. Anyway the cereal box summary is: They meet each other at the closest point between the two worlds and fall in love. For whatever reason, the people of either side of the planet deny people from the other side from interacting with each other and she falls back to her planet and hits her head. Dufus (that's what I'm calling him) thinks she's dead until he sees her on TV and then finds a means of reconnecting with her ... although she doesn't remember him (quelle contrived). The visuals are really quite good but, if you've seen inception (or Ring), you should be pretty used to seeing people walking on the ceiling so that novelty wears off pretty quickly.
And so, to summarise, this was not my cup of tea. This film is like a nightmare that you keep hoping to wake up from ... until you realise you are awake and you are actually watching your mind unravel as you try to make sense of all the inconsistencies. If you do still want to watch this, do it while stoned or heavily inebriated. You have been warned.
