Samhain and Halloween are the same holiday, and Samhain is a Sabbat. Meaning it is to be celebrated joyfully. If people want to get drunk or hang out in cemetaries so what? Pagans don't have to be serious all the time, least of all at Sabbats.
In fact, part of the greatest magick of Samhain is that it is when the veil is thinnest, meaning it is the BEST time to speak to spirits. Spirits are not evil ghosts people play with, and frankly it's just as stereotypically "pop culture" to assume there are. There are many spirits who want to speak to people just for someone to talk to or share messages with. Samhain is the *best* time for it; the only thing that's dangerous perhaps is inviting unhappy or angry spirits into your home or life, visiting a cemetary is not dangerous at all.
