Revenger (2018)

Similar vibes

BOTH:
man and girl/kid form a heroic relationship
man is hero
girl/kid becomes damsel in distress
action packed
genres: action. thriller, crime
very strong male lead
male leads are avenging the death of someone close to them

DIFFERENT:
avenge death of his family in Revenger
avenge death of the little girl's family

Both movie are using different forms of mixed martial arts. Judo, boksing, wing chun, karate and much more. Both movies are honoring the above arts because both lead actors studied these well and peformed them greatly in the movies.
