I won’t lie and pretend I know the history of online dating apps, but I am pretty sure that the last 15-20 years or so are when they began to explode in popularity (two of my brothers met their wives that way).
The thing is, I can not think of every coming across anyone in my life who used an in person match making service like the one shown in Materialists. Still, that is focus taken by writer/director Celine Song (who, I have learned, was once a match maker herself for a few months before becoming a film maker).
Nothing else to say
