Battle of Los Angeles (2011)

When an alien ship takes up residence over Los Angeles, the military are sent to attack and the battle of LA begins. As the survivors at a military base try to escape the barrage of hostile fire, they meet up with a jumpsuited woman wielding a giant sword which can kill aliens. She turns out to be part of a resistance movement. The survivors band together to try to save the city.

That's about as close to a plot as you can get with this movie. From the beginning, it's all biff bam boom - nonstop fighting and explosions. As a joke I had said that I hoped this was the entire movie. Well ,the joke was on me.

Characters come and go without any exposition, even though they are supposed to be different locations the buildings are the same, and for some reason no one seems to realize that if they manage to destroy the space ship, it's going to fall directly on top of downtown Los Angeles.
