I think that 成成 is the best of all...he's smart and charismatic...although he did something bad...you can tell he's actually a pretty good boy...he knows what is right...
The bully however...I'm not very happy with the way his parents' style of teaching...They were simply justifying what he did and does...
This documentary is very good in showing the ideologies of liberals (成成) and dictatorships (劉雷)...Originally I thought the girl might've been more like a communist...but after I watch it again...she just looked like a person that's not suitable for politics...she's more like a typical citizen...
