I would still be interested in seeing a tv series that serves as a prequel to Aliens. It could show how the colonists try to hold off the Aliens as they begin to overrun the colony. It could be super suspenseful too, colonists going missing one at a time, until just the kids are left running around in the vents, then eventually, all but Newt is left.
Other films within the universe would be a neat expansion as well, but if Alien is in the title, there damn well better be an Alien in the movie.
