ALIEN Becomes Less Alien...

You're absolutely right, they've moved away from the principals which made Alien so captivating. However with regards to the Engineers and Space Jockey size difference, I still feel like the Space Jockey was not an Engineer, but the creators of the Engineers. But that discussion is for a different topic.

In terms of bringing the Alien back to being... Well... Alien, I agree there needs to be a change in how the creative team approaches the creature. I think sourcing back to O'Bannon and Giget would be the perfect place to start and from the sounds of things, it seems like this is exactly what Ridley and co. are trying to do with Covenant.

Chris: Sorry if I am a bit late on this but isn't there a risk that they will further un-mystify the Alien with Alien covenant? If they try to explain it then they might risk to make the monster more obvious. Alien covenant seems interesting but I hope that they don't explain everything about it.

Yes fingers crossed its not a Popcorn Spoon Fed Alien Flick.... i.e AVP minus Predators and with a better Cast and Plot point.... No Thanks.

The Alien has still remained as Alien i would argue that the Original was actually more Human than the others apart from the Deacon at he end of Prometheus and the New Born in Alien 3

As far as Space Jockey.... well that was a mess up of Scale... it was intended to be 26ft Tall... but appeared as 22-23ft tall and 13-16ft tall (hard to gauge as we dont see its legs)....  Prometheus started with the concept of 15ft tall, then 12ft.... then 10ft for Prometheus... again scale messed up and well if you try and work it out all we got was between 7.5ft to 8ft Tops...

They can rectify this by using trickery like The Hobit and Lord of the Rings did...  and give us a 10ft Race but they can vary from 9ft to 12ft if they wanted...

Then for why the Space Jockey was bigger...? He grew out of the Chair... and so was really 12ft tall prior to the event.

As far as Less Alien... if you meant Less Giger... then i fully agree.

Right On! Less Human More Giger is the answer. There's a reason why most of us have a least one piece of Giger art in our homes. It makes our imagination run wild.
