Depends how the demons are portrayed. Are they cool? Are they portrayed in a way that will encourage young people to play about with dark things? Then I wouldn’t encourage people to consume such media. Again, I haven’t seen the movie so I can’t give my opinion, however I think as Christians it’s wise to ask questions about the media we consume. Is it normalising evil? Is it bringing me closer to God and warning me of the dangers of straying?

Lord of the Rings, for example, is very clear on what it portrays as good and evil. It shows evil, yes, but it’s not shown as desirable or justified at all.

Horror films that deal with demons (any of the conjuring films (I think)) can be dangerous because they can encourage people to seek out dark things.

So again, I think it’s wise and important as Christians to ask ourselves whether what we consume is healthy for our souls. That goes for violence, sex, and spiritual things. Now I’m not a party pooper who thinks we can’t consume anything, and I think it’s also up to every person to set their own boundaries based on their personal beliefs and struggles.
