A theme park attraction with a content warning? It existed at EPCOT Center!
The Making of Me ran at EPCOT Center from 1989 until 2007. The attraction, which was located in EPCOT's Wonders of Life Pavilion, featured footage of the birth process. Awkward viewing for the family, huh?
The attraction didn't receive too many complaints, but it was retired along with the rest of the attractions in the pavilion in 2007. The final straw for this attraction was the departure of its sponsor, Met Life. The pavilion currently stands unused except for the occasional special event.
