Well for things like this, if it glorifies unbiblical principals then it's a no-go for me.
I have to recall Philippians 4:8 for this one too. I suppose because of the area I live and how saturated it is in the occult, that I'm so adamant against things that paint anything occultic in even a slightly good light. I've seen where it leads, even to those who are strong Christians who begin simply to involve themselves in it.
It goes to how the Word talks about how seeds are planted in our hearts and such, and is why we are warned in the above verse Philippians 4:8 to not take part and give our attention to those things.
However, do I believe that reading/watching those things will send someone to hell? Not at all. It is simply one of those cautionary areas that wisdom cries out not to walk into because it could lead to worse things. Most often it leads to those worse things, ever so subtly that it's not noticed until too late
There are a lot of things in this world that we have to be cautious about. Not that those things are necessarily sinful in themselves, but that . . . . well what we put our focus on, and allow to enter into our minds (which is where the devil most attacks us and is why we are told to put every thought into subjection to Christ 2 Corinthians 10:5, and to gird up the loins of our minds 1 Peter 1:13), will indeed affect us whether we want to admit it or not. So it's one of those things that Christians must be forewarned to be careful about, and constantly keep themselves in check even MORE than ever before if they choose to go down such paths...
