Gotham was not only a giant mental hospital; it was also a giant haunted house. No Gothamite needed to visit a haunted-house attraction anywhere else, because it was bound to be a disappointing experience.
As a Kryptonian, Clark was not very comfortable anywhere without sunlight. The moment he entered the haunted house, he felt uneasy. The deeper the track car traveled and the darker it became, the more he sank into that deep, gloomy atmosphere.
As a demigoddess, Diana truly was not afraid of ghosts, but she found the mechanically made ghost props, elaborately arranged scenes, and flickering lights in the Haunted Mansion quite interesting.
Bruce, meanwhile, was feeling rather bored.
First of all, Gothamites were extremely accustomed to anywhere with dim lighting. After all, before the sun rose in Gotham, the ultraviolet index was probably only half that of other cities.
