The whole thing seems to be a feeble attempt at glorifying exorcism. Best to be careful about serious stuff like that.
I tend to side with you on this. The first thought I had is some teenage girls hung up on Buffy the Vampire Slayer or the Twilight movies. Demonic possession and influence is a very real happening and has never abated even from Christ's time on earth. Anyone who ventures to deal with this problem better be in the correct frame of mind, yielded to Christ, prayerful, sometimes fasting, and at all times claiming the blood of Christ over all. It must be a special calling and definitely NOT for attention getting.
