Currently, Netflix has a five star system. Notably, three stars means "I liked it" and two stars means "I didn't like it".
I would like to suggest another option in between them, which we will call two and a half stars.
Two and a half stars will mean "My ambivalence about this film causes me to explain the many dichotomies in my feelings in Proustian length and detail, and if I may be immodest, in Proustian literary merit as well."
That's what two and a half stars would mean to me.
