First of all, I like Korean movies. And this one didn't disappoint! It features Byung-hun Lee (GI Joe, The Magnificent Seven, A Bittersweet Life), Jung-woo Ha, who is one of my favorite male Korean actors (The Terror Lives, The Berlin File, The Chaser),Dong-seok Ma aka Don Lee (Train to Busan, The Outlaws). This was a good disaster movie in the vein of Volcano and 2012, but with more heart and soul! You get invested with the actors right 'off the bat' With plenty of action and good story-telling, it should be on one's "watchlist". I loved it!
