I like this movie. It's based on a real story and it makes the movie more realistic. I really admire that koreans tend to do this kind of movies showing injustice, as it was for this year's movie Midnight Runners or older movie Miracle in room number 7.
The acting was on point for all of the actors. Kang Haneul displayed the character perfectly, also the actor who represents the lawyer. And the actress which portrays the blind mother did a pretty good job too!

I can't say I have disliked something in particular. I can only say my own feeling is just 8.0 not 10. I don't find the movie too much touching, but it can be this way because I'm getting used to this kind of movies.
