lol, i understand what you mean, i really do, but i'm rather refering to the actual shot.
the shot looks odd, it moves odd. thats my problem with it.
i havent seen enough to judge how it goes in general, but for this shot, it looks odd.
the juvenile version looked great and moved rather awesome and believable to me. very animalistic. not bad, but it gives me a bit of a carnivoreous velociraptor-like sensation instead of proper alien intelligent being. but perhaps the neomorph is really that, animalistic. perhaps the neomorph is the origin creature, perhaps a form of parasite that takes on its host's features which is why it looks like a human being somewhat, and the xenomorph is the lifeform 'edited' by the engineers/anohter race, and david picks up the game.
again, the reason i'm discussing that is because that's all we got. we have nothing else of an adult neomorph but that shot. and exactly that shot looks weird and odd, due to the movement imho.
for the xeno we have multiple shots. it moves gracefully in the corridor, and really good imho. also when it's crawling on the spacecraft, and also when its taking a shower. the only moment i think the xeno moved odd was when headbutting the windshield.
so again, even if it's just half a second, it just moves odd. visually, i have no problem with it though.
i feel like it suddenly gets catapulted from a stand still like it's hit by a canonball in the back of the head.
