Well as you see the story is based on a TRUE event. I must say almost every movie based on true stories are boring to SOME people , and Cart is not an exception ! The only thing that really MOVED me about this movie was ACTINGS ! they were totally great and inspiring. Specially KIM KANG WOO who's a chairman who UNBELIEVABLY gives up on everything he has (money, position etc.) to join a union of some ladies who've been fired unfairly ! To me , this was the most inspiring part of movie "Somethings ARE worth fighting for" ! Although this fight against unfairness could be made even better ! the story moves in one simple line and this might cause some to get bored and even DROP it ! but to me , the actings didn't allow me to ! Totally , it worths once until twice times watching ! but still I insist the whole idea was a good one , But the storyline could go better , more active , more intresting and more REALISTIC ! (I know it's based on a true story but some details looked UN-REAL) When it comes to TRUE stories the real skill of a proffesional screenwriter is to make the story more exciting while keeping the idea - let's say - unchanged ! Enjoy the actings ! and if you are a FAN of D.O , I must say despite his small role he SHINED in this movie ^^
