Elevator Ghost — Funny or Just Mean?

A new viral video has some saying this practical joke is less funny, and more just mean.

"Ghost in the Elevator" was a segment on a Brazilian hidden camera show.  Initially I thought "Oh come on, some people can't take a joke."  Then I watched it, putting myself in the situation.  No longer funny.....just terrifying.  Like, to the point of needing therapy.  Your thoughts?
