I don't really get the negativity for the Alien 5 project. I wasn't thrilled that it would feature Ripley, but might as well. Even if Ripley herself is not in it, every Alien production has a character cut from Ripley cloth. So, fine! Let there be Ripley. And we can have Michael Biehn as Hicks, too. Again, might as well.
Even the worst Alien movie is worth a watch when it shows up on TV or whatever. And as others suggested, it could work well as an animated movie. You can get away with a lot more in an animated movie. The change of medium might be liberating.
As for what our Hicks knows about not-publicly-seen materials... Eh! I don't know what that is, so I've no idea what I'm missing. But I do know that stuff changes from pre-production to final product. What we got might not have been great, but it should have been fun. Hopefully, it wasn't a stinker like The Predator. But even that had its moments.
