"Battleship" is not "The Avengers" but, for me at least, it is not as bad as some have made it out to be. There are remnants of the old game in the movie (note the commercials for the new version based on the movie) that all will recognize but I will not say how it comes up in the movie, but I will say that something similar has come up before in real life in the past either as a real situation or another movie and that the force field takes out all long range communications including GPS so targeting the high end weapons used in the first half of the movie is a major problem. BTW: the battleship in the trailers is the USS Missouri; yes i know it is technically a mothballed museum piece but as with many such ships still afloat, it still has certain "capabilities"; I won't say how or why it gets used. The HUB special on the movie did reveal that all the non-main actors are real navy personnel (active and retired) and that plays a major role.

So despite some of the cliches in the plot I found the movie overall entertaining for myself and worth the $6 matinee price, but if you do not like explosions, alien invasion movies, the military and the like do not go see it.
