I started this drama because it was really popular at the time, so I thought "oh, it must be good", but I didn't enjoy it.

I liked the initial storyline of Seo Joon's character fighting this rich guy's evil son and going to prison for it then vowing revenge, but then the whole plot just kinda falls flat and stops being interesting. You keep thinking something's going to happen that will surprise you and it just doesn't.

I didn't like the character of the female lead at all. She was just annoying. Nothing against the acting there, just hated the character.

Not Park Seo Joon's finest acting, but I guess that's because the script didn't give him much to work with because I think he was alright in Hwarang. His expression just never seemed to change from straight-faced.

But no, from my point of view, I wouldn't watch it again.
