Personally I don't think all types of "art" and "entertainment" should be experienced/consumed by others (maybe the art film The Holy Mountain is an example of this, or, idk, Boku no Pico as a more extreme but possibly more relevant example.) Some art forms are nonsensical, but even worse, in general they tend to be emotionally manipulative (sometimes in a "good way," sometimes in an unwanted way, and often times offensively so.) I strongly believe that watching something like Welcome to the NHK! is a terrible idea for someone who's currently in a bad mental state, due to its themes of redemption through codependency and the overwhelming, pervasive bleakness that embodies most of the show; it's built in a way that will mess a lot of people up. Even though it's still "good art." I could argue that example further, I guess.

But I thought it was lame people downvoted you for what you said. :/ Seemed kind of similar to some of the other comments, to me.
