I skimmed through the Romance genre in my media server. Here’s what I came up with. Not sure if any of these would work.

WALL-E

Dracula (1992)

Starman. He’s not human, but don’t hold that against him.

Warm Bodies, if you don’t mind a zombie theme

Return to Me. A wife has to die, but there’s a nice romance once she’s out of the way.

On Golden Pond. There’s a romance in there, but it isn’t the main part of the story. And they’re elderly.

The Man with Two Brains. True, she’s just a brain in a jar, but none of us is perfect.

Love Story, just don’t believe it when she says love means never having to say you’re sorry.

Little Manhattan, but the romance is on the other end of the age spectrum from On Golden Pond

The Fault in Our Stars
