Interesting blend of comedy and disaster movie. It's not laugh out loud funny but the light tone works and felt I could relax knowing the outcome will be ok for the main characters. It's a survival movie as they navigate out of the sinkhole after the building falls in. Some excitement from daring rescues and heroism make this a pleasing adventure. Some familiar faces including goofy Cha Seung Won and Lee Kwang Soo and Nam Da Reum.
