Upside Down is one of those movies with an awesome premise. The fact there are two worlds on one planet. One in the sky and one down below, how is this possible you may ask? Well my reply would be don't fucking ask me I didn't write the thing you shit. However, I'll try my best to explain. It goes like this. There are two worlds one up above in the sky and one down below, like us, on the "ground". Well each of the two worlds has it's own gravity. The catch is the people from below can't visit the people from above.
The people from above are a rich, successful society, They get lots of sunlight, looks like a blast lots of hot chicks etc. However the world below is quite slum like, full of runts. Boy from below meets girl from above, they fall in love. Want to be together. Impossible cryface....story ensues. Upside Down, for the premise alone is worth the watch. Dunst looks pretty fit in it actually, she doesn't get her chebbers out though. The prude. However if you want to see her Chebbers type "Kirstin dunst Get over it" into google images, you'll see her rack. Surprisingly large.
