Both feature a female lead ghost. The drama special is shorter & has more chemistry between leads than Delivery Man. Also Drama Special free on YouTube = https://www.youtube.com/watch?v=n22E0wEROOk
Both have themes of children (orphans) learning to survive in a war-torn country. A Melody to remember offers a bit more in story than Boys Don't Cry.
Both movies have a mailbox that is a portal between the past and the future............................................
The vibe is totally different for each of these but, both feature a disabled person working in a clean-up business. One clean-up business is a bit more criminal than the other.
Both center around a female who is used & abused, even their deaths will become a mockery unless someone with a strong constitution steps in.
Both set during Korean War. Both have a rag tag team of characters that learn to get along despite being enemies.
Both during Korean War & highlight the innocence among the hatred, fear & bloodshed that war facilitates.
Chinese remake of "Blind." Preferred Korean version, but Chinese version good too. I haven't seen Japanese version yet. Handicapped FL fights a killer in order to save her own life & that of another.
One focused on Pansori & the other on Jeongga, both traditional Korean music art. Each features a strong FL who loves the music & practices to become proficient.
Nodame Cantabile is a longer version of 2 talented musicians that play the piano & become better after meeting/creating a relationship just like the Drama Special Season 1: Pianist.
For both of these specials the piano is the main subject by which the main characters get involved with each other.
Same kinda vibe, but this is a bit campier........................................................................................
