One of the best Korean dramas produced, it is a Korean mafia Godfather show. There is plenty of action: fighting, shooting, stabbing, killing. The suspense with all the revenge, mafia hits, betting, and takeover moves will keep you guessing until the very last scene. My favorite part was the intense love story between two of Korea's hottest stars, Lee Byung Hun and Song Hye Kyo which weaves through the entire drama. Add to that Ji Sung and a huge exceptional cast. This drama feels very real and scary at times. There are no silly cartoon characters or fill in empty stretches. Don't let 24 episodes deter you. I didn't want it to end. Also, the loyalty between childhood friends, which extends into teen years and adulthood, is very heartwarming. Most people just watch new shows, so All In no longer gets attention. But it was a big scale production in 2003 with breathtaking scenes from Jeju Island all the way to the Grand Canyon and Las Vegas. It was extremely well done and is not dated at all. If you are a fan of Lee Byung Hun, you will find his acting, karate skills, and lovemaking exceptional here. All In has it all!
