Battle: LA is one of the many alien movies to be coming out this year, and it seems there is a good chance is will be the best.
The story of Battle: LA is that meteor showers hit multiple cities across the world. The main character is a Sergeant Major who is planning on retiring. While training Marines they all are called into a deployment zone. Eventually they're sent out to get to a police station to find and rescue any survivors, and to do this before a planned bombing raid happens. On the way there they platoon is attacked, and so ensues the battle for survival and LA.
Battle: LA has great mix of story telling, combat, and tense moments. All in all the visuals are a great sign, and this movie not being in 3D is a plus.
In such, Battle: LA is a definite theatrical watch, and an eager wait to buy.
