This drama reminds me of All In and I am not even sure which was better, I guess All In made more sense and was more into gambling, this drama is more into everything else, like explosions. Like in many dramas of this writer (and ahem, director) there are so many details which are kind of ridiculous, at some point the show becomes a bit boring but there is this magical feeling which makes you to come back to finish. This is a typical drama about gambling, revenge and first love which never dies. There is a lot of plotting and action but the romance is left on the backseat, I wish there was less of it because the romance part is also the most boring. But anyway, if you are sick of all the romantic stuff and want to entertain yourself with action give this show a chance. The beginning is slow, the whole drama is kind of slow but it doesn't matter much. I really like the feeling, the atmosphere of this drama, it is very addicting. Even if I don't understand why some Koreans were hired as hitmen and sent to Africa to save a prince of some tribe. What? Yeah... The ridiculousness is part of the charm. Acting is okay, I mean Ji Sung is in this show, what else do you need more? Well, except Sung Yu Ri, I totally hate her because whatever character she plays becomes really annoying and she can't really act. Then So Yi Hyun, Lee Wan, Jun Kwang Ryul and Ma Dong Suk. I freaking love Ma Dong Suk! The cast is just wow and they do a great job! The plot is entertaining and complicated even though some things become pretty obvious as episodes pass and then you just wish for them to be revealed sooner. Give this show a try, it's not like all the other dramas out there. But if you must choose, All In is better.
