Ideal world

I saw this movie the fifth element and it was about this evil blob of the size of a star is trying to crash into the earth and kill every thing so that it can elimiante all life which is its perfect world, no life. But theres this ex milltilary person and taxi driver is trying to have a normal life but this lady comes crashing into the guys car and then he eventually finds out that he needs to save the world and through a bunch of series of events he does. its like every movie out there the key thing to saving the world is love and the world is saved at the last possible second and then they live happily ever after.
