Ignore snotty reviews from so-called professional critics whose "sophisticated cinematic pallet" Battle LA does not satisfy, if you want dialogue watch The Kings Speech, if you want in-depth character development watch Band of Brothers! BLA does exactly what it says on the case in fantastic action-packed fashion.
Set on the backdrop of global invasion for Earth's water supply (as fuel) we follow a squad of US Marines headed by ageing combat vet Aaron Eckhart as they struggle to fight through "The City of Angles". Plenty of gritty battle sequences with superb effects, its more like a war film with Aliens rather than a alien film with marines, creating a somewhat believable scenario. Also, it was refreshing to see that the invaders weren't force-field protected, ray-gun toating, impossible to kill Martians for once (thats not a cliche is it critics???) but use explosives, firearms & aircraft much like our own military (albiet much more technologically advanced), again making the film more feel realistic (to an extent!). You'll also see borrowing from sci-fi greats such as Aliens, Independance Day & Ridley Scott's Black Hawk Down, but this feels more like homage than plagarism. Also, the camaraderie between the Marine feels very real, with a great performance from Eckhart & Will Rothhaar as Cpl Imlay (suprisingly Michele Rodrigez plays a character I don't completely dislike for once).
Yes, the film uses text book war film cliches at times & some of the characters are left a bit untouched (in particular Doc Adukuwu & the female civilian) but I didn't notice this too much & throughly enjoyed the film.
In all honesty, you'll have already decided wether you like this film & want to watch before reading, if you don't - your loss. If you do - Battle LA it won't disappoint!
