Its like anything in life though...
Theme Parks for example, more specifcally Roller Coasters, esp the ones that make you feel like you are close to death for some reason, unknown to us, theres a frill of it to us sickos....
Same with what genre of film people like...I loath / hate / despise 'most' chick flicks id rather slit my wrists and stick pins in my eyes Id much prefer to watch a film with something exciting and maybe not quite normal in it, as to me thats more entertaining 8)
Now rollercoasters, I LOVE but it doesn't involve me having to endure the sights and sounds of someone being brutally raped or having their head smashed in with a fire extinguisher *insert pukey smiley*
