A man posting on a Japanese marriage advice forum has said the reason for his wife divorcing him was that he didn't enjoy the Disney film Frozen.

He writes that his wife became obsessed with Frozen after a friend introduced her to it, prompting her to see it at the cinema numerous times. He was eventually cajoled into going along with her, but afterwards said that it was only "OK", and he "didn't really care for it personally".

Perhaps inspired by the self-empowerment message in the film's central anthem Let It Go, the woman then said: "If you can't understand what makes this movie great, there's something wrong with you as a human being!" before saying that she wanted a divorce. He says she now won't talk to him directly, but mediates through their parents.

The man states on the forum (ominously titled The Gravesite of Married People) that there were no pre-existing issues in their marriage, and that he earns enough for her not to have to work. Forum users have since offered advice such as: "If you've got that much money, you should hire a private investigator to look into what she's been up to. I bet she's seeing some guy on the side," and "That's just weird. Do you think there's some other reason she ran out that she's not telling you about?"

The woman isn't the only person to have been swept up in Frozen's spindrift of sororal love and peppy songcraft – it has become the most successful animated movie of all time with $1.23bn in revenue worldwide, and is now the third-highest grossing film ever in Japan, after Titanic and Spirited Away. It has prompted Oscars, a bestselling soundtrack, a spinoff ice-dancing show, and parental frustration as stocks of tie-in merchandise dwindled faster than expected.
