I don't understand the continued obsession with her mythology,

Homos love Marilyn Monroe. They fetishize her (listen to Elton John's "Candle in the Wind" for the cult's theme song).

Feminists also fetishize her because she slept around and felt guilty because of it. Of course, all the men in her life are to blame as women who sleep around and get fucked over are innocent victims of the patriarchy.

Her end was tragic--she was passed around by some very powerful men and either Kennedy's henchmen poisoned her to avoid a scandal or she snuffed herself out of humiliation and regret.
