There's a very strong misconception about biblical depictions of Gods, angels, demons, ect.
The entity in this video is an angel. The message of the movie is christian and anti-human. I watched it a while back and while the scenery was done well (with some innacurasies, the ritual in the movie was not a ritual of Abramelin and it wasn't gnostic, it's clear the movie makers had no real knowledge of occultism), the point of it was the mother was summoning an angel to kill some men who murdered her child, or something like that, but in the end decides to forgive them as that's the "mature" thing to do.
In the bible, angels were always depicted as humans when they appear to humans, except the "biblical accurate" ones which were the "higher" angels and only seen in visions in Ezekiel. There is no actual description of how demons look like, besides the book of Enoch which says they're just like humans. The whole Goat horns and hooves was stolen from Pan and this became the commoner depiction of Satan. Biblically it says Satan can appear as an angel of light or that the Demons, as "sons of God" are implied to be human-like, or in other cases lacking a body and possesing other humans or creatures.
Having said this, association with Satan/"evil" with the goat is present in the bible, through the parable of the goats or the yom kippur ritual. This is different from outright depicting Satan as goat-like, which is actually an allegorical, Pagan depiction.
Accurate depictions of Gods/demons is just making them look human, which a lot of movies actually do, even if they're painted in a bad light.
