"Drama" is perhaps the broadest genre when it comes to art, films included. It's a descriptor that gets paired with plenty of other genres, and broadly applies to movies that aim to show the human condition in some way, usually through portraying realistic characters who are challenged by everyday - and often relatable - struggles, often with other people. Character-focused sci-fi or fantasy movies can still be considered dramas, as can comedies, if they have enough serious material (in turn becoming dramedies).
