Take a look at the Neil Blomkamp/Sigourney Weaver short film called Rakka.

A little bit Terminator, a little bit Aliens, and black goo... A lot of black goo... Black goo as weapon...

That was pretty cool. 

It seems that he regurgitates the same style from District 9 and Elysium, so I'm not sure that would be good for an Alien film.

C'mon, Ridley! Get on to the next one already!

That is exactly the sort of thing i was hoping for expansion of the black goo idea in AC (not the lizard people part) something bigger and taking the idea further but instead we got David :( . 

Bit rough round the edges. Some things are bit off. But also some nice ideas and concepts. All in all not bad.

Lilly,

Is that a giant poop the lizard-people just dropped on us?  Oh my goodness I am not mature enough to get past that!  The methane cloud is killing me!!!!

Something other-wordly & scary, not lizard-people would help me, though I am still a Sigourney Weaver fan for life!!!

Thanks,

CB

I will watch this after... i wonder if this was done as a way for Blomkamp to actually tease a few ideas he had for Alien 5

So that those who saw it would see "See this is kind of what we could have been seeing instead of Alien Covenant"

Swap Lizards with Engineers, or Xenomorphs.

Interesting. Some of it looks cool, some not, but it's kind of the same old stuff from Blomkamp. It looks like a remake of V mixed with District 9!

Very cool!

Was trying to visualize this set in space or on a alien world. Earth is a cooked beast.

Looks like crappy syfi channel stuff. 

So lizard man beat the earth by dropping massive amounts of shit ( excuse me, i mean excrements) on it, causing global warming,storms and a hard to breath atmosphere.

Yeah seems right.

I give it 5/10.

The aliens looked cool somehow (but too cliche a bit, i mean lizards?! comon) but that black substance  is ridiclious.

Less of it would be more believable but here it looks like they have not enough funding (or ideas) to make nice looking alien structures but replace it instead with ugly/weird CGI effects.
