If you've been following the development of the forthcoming sequel Aliens vs Predator: Requiem, you'll know that it features a 'predalien'. However much you enjoy the Predator films, as soon as you see that daft puppet the balloon bursts amidst prosaic doubts over the viability of interplanetary reproduction.
