Having invested 30 hours watching one of the best revenge dramas I've seen in awhile with the best acting cast! Even though I was not totally for the ending, this does not overshadow my overall feelings for this drama! Talk about family dysfunction to the 10th power!! The cast was stellar! What a great comeback for Joo Ji Hoon who I loved in his prior works! Seeing that he was blacklisted for a period and he completed his army requirements, it was great that he came back strong! Chae Si Ra? I am now a fan! She was wonderful as the twisted mother! Ji Chang Wook was a newcomer to me as I had never seen him in anything before but I will remember his name. Cha Hwa Yun as Madame Na, this has to be the first time I've loved her character!! This definitely ran the gamut from mental abuse to revenge and it was well served. Great job by all! Cannot wait to see them in the future!
