I rarely cry at movies, but there are two that really made me tear up:

The Impossible, a film about the story of a family separated during the 2004 Boxing Day Tsunami, starring a much younger Tom Holland. The family reunite at a hospital, the three brothers first, then the father, then the injured mother.

The Lost Valentine, starring Jennifer Love Hewitt and Betty White, telling the story of a woman, Caroline Thomas, who’s husband went MIA and was later found with the help of a Journalist and her boyfriend. The scene where Caroline is reunited with her late husband’s coffin is heartbreaking.
