Star Trek. The aliens can't move from planet to planet, Starfleet could park a couple of ships in orbit and blast them. I guess it depends on what version of Star Trek we're talking about. Old Trek, the aliens are toast. New Trek, they'd be down there trying to give the aliens a hug because "muh diversity!"
You guys beat me to it. Yes, they completely ripped off the Alien franchise, right down to having a Newt character. But I wouldn’t call killing off the most tedious character and sending the second-most tedious character off on a pilgrimage a cost, exactly. More like a fringe benefit.
