What should've been an easy blockbuster story (alien scouts come to Earth to kick-off a full-scale invasion) instead was a series of befuddling events and circumstances: What was that whole red/green thing in the alien POV shots? Why did the aliens not just kill indiscriminately, if they were planning to invade? What the hell were they after, exactly? Were earthlings the villains all along?
Indeed, upon closer examination (of anything besides the slick visual effects), it seems as though Battleship wanted to tell a larger, deeper, story - one that possibly could've kicked off a franchise of films dealing with the alien threat. Too bad it never made it into port.
Sequel? No thanks.
