The year is two-thousand and three-thousand and ... look, it's the future. Humanity is threatened by some bug-like things? Bug are good bad guys right? Look, they have ships that are various shades of red and quite threatening in shape, and they shot us first probably. Stop asking questions and fire those torpedoes!
