The base idea is nice, intriguing and exciting.. But somehow i feel like there's something missing or not quite complete in the execution and story telling.. The awkwardness during delivers of some "cool" /"key" moment.. Like that "engine" scene when SJK talking bout his company.. The "romance" between ML and FL and 2nd FL (the granddaughter in-law) is a bit forced, sudden or like a bit out of place.. But the base idea was really good.. An ML that went back in time but as someone from the family that cause his death.. With his knowledge of the future, he strives to get revenge and succeed against his enemy..oh.. And the seniors actor/actress acting and their character is very nice..
Ofc this is just my personal pov...
