I'm a Cyborg, But That's OK

A 2006 South Korean film by Park Chan-wook, starring Su-jeong Lim and pop sensation RAAAAAAIIIINNNN!

Best described as "a Romantic Comedy that takes place in a mental institution and features a love story between a girl who believes she's a cyborg and a boy who believes he can steal other people's souls."

......

Yup!

While critically acclaimed, the film had disappointing sales and box office numbers, possibly due to how completely different it is from the director's other works.

 * Character Tics: Considering their mental state, it's understandable the characters all have them.
 * Young-goon talks to electric objects wearing dentures and attempts to shake hands with people (who she actually wants to shoot).
 * Il-soon wears masks based on other people's faces, hops around like a rabbit and brushes his teeth when upset.

 * Consummate Liar: Sul-mi, one of the patients in the institution, is a mythomaniac.
 * Cue the Sun: The final shot is of a beautiful sunrise.
 * Did They or Didn't They?: It's implied, but never confirmed, that . Considering they're both cloudcuckoolanders, anything could've happened.
 * Does This Remind You of Anything?: The whole Rice Megatron scene.
 * Electric Torture: The shock therapy is portrayed as this. Sul-mi actually loses her memories every time she has it.

 * Force Feeding: Young-goon is subject to this since she will not eat, with pretty horrible and realistic results.
 * Gadgeteer Genius: Mentally unstable or not, Il-soon shows off his creativity and skills, the Rice Megatron being the sum of all this. It's explained that he used to work as a technician.

 * Reading Lips: Il-soon is shown to be quite good at this when interpreting a distraught Young-goon. It comes in handy later.

 * Rule of Funny: See Willing Suspension of Disbelief below.
 * Toplessness From the Back: Played with. When Young-goon takes her top off in front of Il-soon you'd certainly expect fanservice, however instead we get to see how thin and frail she has become. Il-soon is clearly distressed, although he still touches it for good measure.
