I usually like the revenge vigilante plot in dramas.
Everyone's acting was good.
My favorite character was definitely the copy cat Vigilante..
My least favorite character was the woman reporter.
the fighting scenes were great as well it fits into the overall story and does not stick out like a sore thumb. Gruesome scenes were gruesome.
I think if there was just a little bit more emotional investment - building up the characters emotionally (for example the victims) may have invested me more into the show but they only showed the criminals in the act or after it.

Story was fine.
It's a good watch but very average.
