According to director, aliens are NOT an evil invading force...
Via an online interview with Battleship director Peter Berg: "There's a group of life forms from some other planet have come to our planet for something. They've got a very specific agenda. That agenda is not global domination. It's an agenda and that agenda puts them into conflict with members of our military."
And...
"The alien race (called The Regents) come from a different planet than us but one with a similar ecology to ours. However, the interesting part is that Battleship will be set apart from most other alien invasion movies in that the aliens aren’t coming down to destroy or take over, but are looking to build a huge power source in the ocean. This “goal” inevitably brings them into conflict with us and our battleships."
Guess that pretty much settles it.
