The trailer for the Hasbro game-movie “Battleship” has been released, and for the most part, the trailer makes you wonder why Universal even needed the game as a basis for the movie.

The trailer (embedded below) shows the main characters–Taylor Kitsch as Alex Hopper, Liam Neeson and Admiral Shane, Alexander Skarsgard as Stone Hopper, Rihanna as Raikes, and Brooklyn Decker as Sam–in their establishing relationships and roles before the big threat of the film, a ship of unknown origins, threatens the navy ship most of our main characters are on. And, like all alien invasion films, the alien ship (or ships?) are also a threat to the safety of the world.

The blurb on The Daily Beast’s post about the trailer asks, “Transformers goes underwater?” It really is an apt question, seeing how one of the soldiers touches something on the side of the ship that awakens the alien ship (and, of course, the mysterious thing has some eerie blue light shooting out of it). And the alien ship looks like a Decepticon.

But even with all of my griping, I’m a sucker for alien invasion movies, so I’ll probably go see it when it comes out May 18, 2012. After all, nothing says “summer” like a movie full of people fighting aliens.
