Well, i think that it makes every sense to create a Predqueen, and i also think that was a brilliant and brave. FIRST, because it think the audience needs something new (there were 4 aliens movies). AND SECOND, why do you think Ripley was chestbursted by a Queen? Aliens seem to acquire several characteristics from its host. Temper, bravery and lately, fisical characteristics. (Ripley was a great warrior... ). I think it´s a natural resorce that the Aliens have to perpetuate the species, to improve it and to servive...
