I always wonder why does US navy, army, air force always seems way awesome compared to army forces of other countries. Maybe its only in the movie, haha! After watching this film, I grew a sudden urge to join the navy force yes haha, the show had that kind of effect on me!

Having watch so much movies for 20 plus years, its obvious, aliens are becoming more and more human like, intelligent and advance. They always seems to own equipments containing technologies not yet invented on Earth. 

Alien battle on sea, not bad :)
