Battle of LA. Worst movie ever.
Spoiler
There's a big *** command and control space ship in the movie. The marines take it out with one missile and make it seem like they were geniuses they came up with the idea of shooting the ship with a missile and then make a point of letting the world know how to take them out.(like on Independence Day) Also, at the begging of the movie, the aliens were unstoppable, then they conveniently find out their heart is located at the same place where our heart is - by the end of the movie, 2 dudes are driving away a group of aliens without cover and with some pistols. Fail, movie writers, fail.
