Review title: Lots of action but little substance.
Product review: There are too many loose ends in this plot and too many stereotypical characters to put it in a "great si fi" category. Troubled kid brother joins Navy to follow his older sibling who (of course) gets killed by invading aliens that look disconcertingly like Old order Amish sporting porcupine beards! And speaking of Navy, clearly that service had a hand In the production....probably a recruiting ploy. Seems the Blue Water Navy saved the world all by itself. hoo-raa!
