If, in the years since Lena Dunham ascended to pop-culture prominence upon the debut of HBO’s Girls in 2012, you have felt some irritation with Dunham for the apparent self-absorption, even self-obsession, she projects in essays and in squibs on social-media platforms, let me say: my friend, I feel ya. This is also true of what is now an array of men who’ve been treated to what we might call The Hannah Horvath Experience. The new season starts with Hannah having published an essay in The New York Times’s “Modern Love” column that grew out of last season’s triumphant monologue delivered at the storytelling showcase MOTH (Dunham always gets the little Manhattan-striver details right).
