The spectrum is wide.
It's not just love story movies.
It can include movies that are not love stories but have a scene of love or a minor sub plot that has impacted you.
Also not only romantic type love between two people like in love story movies,
but the broad spectrum of love one can express and feel from various relationships.

I've gone through my huge list of favs and was not surprised to find that love features in just over 20% of all of them.
