I see they’ve already decided. But I have to recommend “Return To Me”. A very overlooked romantic comedy. But my true love is older movies. "Philadelphia Story " (or “High Society”), “Bringing Up Baby”, “Father Goose”.
I guess for the true romantic schlockfest, I’d have to say “An Affair to Remember”, with Cary Grant and Deborah Kerr. It was parodied in “Sleepless in Seattle”.
