Arcadia was too much of a MarySue ship

Seriously there should have been some kind of struggle during the battles. But all we saw was Arcadia blowing through swarms of so called battle-ships time after time so it got really boring and frustrating. Those other ships that apparently could not hit the side of a barn much less the side of a ship with those THOUSANDS of blue beams??! They seemed to want to shoot everywhere...EXCEPT at Arcadia!
