this started really really really good!! at first I love it so muchhh, I really love disaster survival kind of genre and this one, plane crash and deserted island is so unique to me (as there is no other drama with the same setup). And since there is 2 timeline, I even find the present timeline annoying cause I only want to watch them surviving. Ugh I love itt!! oh and btw I thought it will be some serious heavy dark drama but it's not. It has lots of funny parts in it especially the two main characters, seo joon oh and bong hee. but sadly it last up till the 11th or 12th episodes :( after that it went downhill. there is switch of genre, which i don't mind honestly. but the could have done better really. and the most disappointing one is the ending. like after all those hardships they end it just like that? especially for choi tae ho. ughh this drama really had its potential but since I love more than half of the drama, i give it a not too low rating.
