Not the one you asked the question to, but for me, it was so different than anything else I had seen on film or even imagined. It wasn't necessarily scary, just uncomfortable, completely in the dark about what it could be capable of. scary more due to the unknown of it vs oh there's some claws and mouth, I know how it can hurt me.

It was because of the scene when the group of of people were sucked in, but still alive and screaming. Then there was a moment where it was implied that they might be able to escape or survive until that fucking thing digested them and there was silence.

The pure terror, then tiny bit of hope followed by more terror AND pain followed by the nothingness is just too much. Brilliant, but fuck that.

It's cool looking, but not "horror movie monster" frightening... more like an aquatic-esque flying creature.

No, and be thankful for it.
