If you loved Hula Girls, try 69
A bridge between a film you've already seen and one most people haven't. 69 has roughly 3.7× fewer votes than Hula Girls — it's a deeper cut, not a mainstream recommendation. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Sang-il Lee, and they both carry the bittersweet mood tag, and they sit in Comedy / Drama territory. If that's the register that drew you to Hula Girls, the second film will land in a comparable space — through a different lens.
What 69 is
Ah, youth. Here's a film about it. Two high schoolers scheme to throw a festival of film, theater, and rock in an effort to get laid. Instead, they attract the attention of the media and the police. A fairly accurate depiction of adolescence, then.
