I generally don't really care about most stuff that is "popular" because who am I to judge, but if there was one thing that is actively harmful for being popular, it'd be Fifty Shades of Grey. Completely inaccurate and harmful views of BDSM, outright sexist views of women (written by a woman, no less) and their relationships with men, and overall preaching harmful views of sex and relationships. It's a problem because Fifty Shades is easily the most-read BDSM book ever, making it dangerous for it to preach unhealthy habits to such a massive audience, to the point it could very well lead to abused women believing their partner is doing it out of love or that they should just take it rather than attempt to get out of an abusive relationship.
