So, basically, they rewatched the old 'Firewalker' episode fo 'The X-Files' and decided to shunt it into this.
It's really not original.
What's interesting is that it essentially vindicates my original prediction: The next film-maker can do whatever they please and Fox's earlier declarations regarding canon status really do mean nothing. If true, these story details effectively retcon 'Fire And Stone' (and everything which came off of that) as no longer canonical.
If this is what happens with the black ooze, all those characters stranded on that world in the ecosystem from the new comics, should have all succumbed to this fate.
Hope they don't do literal interpretations of that albino whale concept art, though. Those things always looked as awkward and chunky as f**k to me. Definitely not as iconic without Giger's typical biomechanical detailing. Maybe if they added that sort of aethetic and made it look properly intimidating, instead of just a white slab of lard with teeth. Size, alone, was not what made the original classic design so intimidating or timeless.
The normal xeno isnt scary anymore, its just cannon fodder.
'Alien Isolation' (and the two original films) prove that assumption completely wrong. It's all about presentation.
Having a tall slim psycho looking xeno wich is far superior in everything and having the mind of ten smart Einsteins all based on how to kill you off as nasty as possible, and being as fast as a cheetah, this thing coming after you in a ship or jungle, you cant even outrun them it doesnt even hide in small vents, it just comes at you for one thing and when he lunges at you, those long nasty white strong fingers go through your eyebals like a hot knife throug a small newborn baby. (was that over the top? i never can tell 
But... That's practically what the normal Alien design already does.
I didnt find the xeno in Isolation scary, the way it moved was a complete laugh to me, worker Joe on the other hand was a complete nerve buster and scarier then a xeno, ehm the first two movies are irrelevant in this, its about the new presentation.
I see the old xeno as an old car that was hot back then and fast, lets say a Ferrari its now as fast as a standard BMW.
A big black clunky xeno doesnt cut it anymore, you need a fast flexibel strong creeper and he has to be huge to scare the shits out of you.
There is no way in any presentation that you can make the xeno scary in this form at this moment,
we all have seen it way to much, it isnt a mystery anymore nor is he undefined anymore,
the AVP movies have a part in that and Alien:R and Aliens also a little, i loved Aliens but it took away every aspect of horror away from the creature/thing.
