simple opinion without any spoilers

Rating: 6/10 (10 April 2020)

1.This movie is too over rated, I don't know, maybe it is something wrong with me because so many people appreciates this film superlatively...
2. All the characters are pathetically unlikable. They only show flaws. You don't want to be them; you don't want to be with them ... not at the beginning, nor in the middle, nor in the end.
3. This lowlife 4-member family was at bay and struggled to a barely survived condition, the husband/father was unemployed for a very long time, the wife was nothing but a mean heartless woman, the son and the daughter had failed the college entry exams for so many times. This helpless and hopeless family couldn't simply become a well practiced con-artist family overnight. If they were such great scammers, they would not have fallen so low and so helpless for such a long time. They don't have money to afford a dignified basic living standard. They would not be possible to suddenly become expert con-artist so easy and so soon.
4. I don't understand what the intention of the director is? What does he want to explain or to prove? Is it a critic of social inequalities? Is it a thriller? A comedy? I don't know and none of these styles is addressed adequately.
