Would I be interested in another Alien movie?  You Betcha!
But how to follow Ripley's Christ-like/Tooth Mother sacrifice at the end
AIII?  Resurrect her?  Anyway, keep the lead a STRONG female.  I assume
we'd finally get to see the bugs' home planet and discover if they have
more actual intelligence than a cockroach.  (not that a cockroach needs
more than it already has).
