Quick story review
The Lego Movie, is the first full time (Everything is Lego) movie. Literally, everything is Lego! From the ground to the sky, everything is Lego! Sorry, I said (Everything is Lego) like three times. It all starts with the most ordinary guy in town. He is accidentally mistaken as a really cool guy who is supposed to save the world!
The 'Prophecy', is that whoever finds the Krazy Glue cap, is considered the 'special'. And whoever finds it has to put it back on the Krazy Glue tube. Then he\she would save the world, because it will stop Lord Business from using it on harmless people.
