Its a rollercoaster, and by the looks of it a good themed coaster. All this whining about it being "controversial for families" due to the lore surrounding the ride is utter chicken crap. Kids and adults will still go on it and they will enjoy* the EXPERIENCE of the ride (*unless rough) which is intended.
Going off topic but look at the legendary metal band Iron Maiden, they have an album/song named Number of the Beast, still regarded by many as their best album. What I am getting at is parents let their children listen to that song/album because they enjoy it.
Same with other bands, Ghost in particular, heavily into the satanic stuff but its just music, same with the ride, its just a ride at a theme park.
Ultimately, if people don't like the content/experience then don't listen/ride. Instead just stay at home and close the curtains.
