They knew what they are capable of and acted accordingly, like Spielberg and this wrecked cursed doll in Jaws. They cut every scene keeping in mind that they should avoid giving away how fake it really looks. With these dynos it's the same, they constructed the picture in a way these rubber water hoses fit in.

There they kept that seemingly unfair close shot and oked it. More than that, direct shots right-in-yer-face are usually avoided because they are always uncomfortable even with real actors, but there they doubled down and got the best of uncanny valley effect. I feel like it's more plausible to be a sabotage rather then incompetence.

On other points I agree, gfx jumped seven miles just between these to pictures, but technology can't replace good taste and basic sense.
