Crazy fun and drama from Korea. They seem to love this genre and do it rather well. O.T.T maybe but gripping at times, funny, silly, sad. Never boring. The idea of the power dogs being conditioned for terrorist hunts was believable. The car pile up in the fog a bit unlikely maybe. Variety of eccentric screaming characters and the cliché teen girl bossing serious divorced dad, who is in the security side of the government, a predictable norm now in much cinema. Not convincing really but quite good and many will enjoy this romp. Glad E9 survived the drop and the abuse from humans.
