Seo Bok (2021)

Both are science fiction based movies with Similar powers, and themes as well as special effects. If you like one you'll like the other.

If you love Sci Fiction with a mix of horror you would like, The Silent Sea and it also stars the great, Gong Yoo.

ML is the result of human experimentation and not treated as a human by those around him. Tragic and very sad ending.

The tone and vibes to these films are totally different but they remind me of each other in terms of the human experimentation aspect, as well as there being a whole special ops team of people trying to track down and kill a genetically modified human-thing. Young-nam Jang is also featured in both films.

ML is the result of human experimentation. Dark themes. While Duel has a more upbeat ending, neither is perfectly happy.

they're completely different but the male lead in seobok and the female lead in the kidnapping day they are both treated like experimental subjects and they both need love and sympathy ..

Very different story but I was remained of Seobok while watching Alienoid. Both movies are sci-fi, has non-human main character, special powers, action and in both are parent/child relationship but they're not actually related by blood (in Alienoid it's Father/daughter relationship, in Seobok it's not entirely family-like relationship but I got fatherly vibes from their interactions)
