You honestly believe that watching movies and tv, wearing costumes and even regular clothing and getting tattoos and piercing will result in a person going to hell?
Yes I do:

The popular culture, as promoted by the anti-Christian Left, pushes this stuff for a reason. It is not the seemingly innocent fun it purports to be. Electing Mitt Romney next week, God willing, is only a brief delay of the inevitable, if we do not turn our TVs OFF, if we do not work to get as many kids as possible out of the public school system and it’s anti-Christian culture in the short time we have left.
All human beings are flawed and sinful. That is what results in human beings going to hell.
Refusing to submit to God's will, refusing to submit to Christ as Lord and savior, is a rejection of the lifeline that God made available for all people by sending Jesus to live as a human being and die as a sacrifice for our sins is merely continues the default position that all human beings are destined for hell if they continue to reject God.
The cultural result of a humanity that is separated from God and that collectively rejects God's will manifests in growing secular acceptance of sinful behavior (homosexuality and other sexual sins, blasphemy and other mocking of God, theft, murder, and so on). As Romans Chapter 1 also notes, a culture that rejects God will be given over to its sins -- it celebrates sinful activities through its music, art, politics, economics, and all other aspects of life.
In doing so, the culture attempts to convince its members that God is unnecessary and that they can achieve perfection, happiness, enlightenment or whatever their spiritual goal on their own terms. The homosexual community is a perfect example - that community rejects God and attempts to convince itself, others, and potential members that there is nothing wrong or sinful about its activities.
To answer your question, then, merely watching an occult movie that celebrates violence, magic, and death does not send a person to hell. It is a symptom of being out of a right relationship with God.
