If you're going to the cinema with the expectation of this being another mediocre alien invasion movie, then you're right. Battle LA has gone for a more realistic look then most alien invasion movies and the cgi is impressive to say the least; but even this doesn't help the drab plotline. Over the course of the film you follow a platoon of U.S marines lead by Aaron Eckhart trying to save civilians and get out of the infected area before it is bombed. Despite the cliched plot and script, the cinematography is impressive and gives you the feel that you are among the soldiers. Although the film is extremely pro-American, it is generally exciting and if you are the kind of person who loves movies packed with gun fights and explosions, don't hesistate on going to see it.
