I watched "Vigilante" because of Nam Joo Hyuk (I adored him in "Twenty-Five Twenty-One and Start-Up" )
I love the fact it only had 8 episodes (16 is too long for me).
I loved the story and the actors even though a little heavy on the violence side and no romance whatsoever, but I still enjoyed it
However the ending I wasn't of fan of, but then I read they are supposed to be doing a Season 2 (if that happens, then I'm ok with the ending).
For me, it was awesome!
