Scott can not be trusted, once more. The fact so much has been given away in a 2:30 trailer just as it happened before with prometheus irremediably points in toward that possibility. Yes, the trailer is very cool and all that, but so was the trailer of prometheus back in the day, and look what happened eventually.
Also, so underwhelming to finally see that we won't be rolling back to the old human-like behaviour/way of moving around displayed by first alien. We are again given an animal alien, no matter it spawns from a human host. The so called Neomorph seems to display same animal behaviour/way of moving as well, when it could have been an incredibly disturbing thing to see this thing moving like humans, or just like the first alien did. It also doesn't seem fully grown to me. It's small.
It was making it like a human what it was truly disturbing, scary and mysterious too after all, not the other way around.
