What would happen if the world got so warm that the ice shelves of Antartica broke off, the glaciers melted and the oceans became less salty? Why the whole Northen hemmispher would plunge into an immediate iceage of course.
But don't worry, Spiderman comes to the rescue. None the less, I have enjoyed this movie several times. The special effects are spectacilar. The cast is enjoyable and the dialogue is not so bad that you would loose your popcorn.
This is escapism at its best.
