The part that I find dangerous is NOT teaching people that in real life, when you run into contact with or influence of "dark energy" or "dark forces" of occult, sorcery, witchcraft, demonic obsession, addiction etc, the cure for this is to remove the influence by prayer invoking the authority of Christ Jesus. That is the one source of strong enough positive/concentrated healing energy that can overcome and defeat the negative controls from occult energy.
This is similar to warning people of the dangers of exposure to microwaves or other "radioactive" energy which isn't like normal energy levels that are natural. The stronger the "radioactive" energy, the greater need for protective gear so people are not exposed directly to energy that can cause cancer and other ill effects.
People do not take "occult" and dark energy/forces seriously, but it has been linked to mental and criminal illness, at levels that lead to deadly addictions and both homicidal and suicidal deaths.
So when these dark occult forces are represented or advertised as if people can overcome them by themselves, this becomes irresponsible and unethical. I'd prefer to see greater educational outreach and awareness, including scientific research studies and warnings of both the dangers, signs and symptoms, and the remedies and where to go for help at first onset.
One real life example of someone trying to warn others of the dangers of occult and dark forces is David Berkowitz, after he went mad and killed several people under the influence of occult obsession.
The treatment, prevention and cure through Christian therapy to remove the occult influences is well established, but isn't fully understood by the public. This requires further medical research studies and development to prove how both the negative and positive energy work, and then that would help establish this as part of medical science and mental health treatment.
What you bring up is just the artistic depictions. But the real issue that Christians are addressing is the real life influences of these dark occult forces, the effects on people's health in terms of addictions and suicidal or homicidal behavior, and the cure to these problems.
