Expected something similar to Battle Royale and almost decided not to watch this, but i'm glad i did. If you are looking for a thriller which makes you wonder if the characters will survive and if you care about the characters more than the plot, this is for you! The plot is pretty simple, a school bus drives off a cliff during a school trip and leaves the survivors struggling to survive, yet they managed to make this drama entertaining. By focusing on each characters story left a lot of space for the character development and while not all of the remaining characters did not get all the development they deserved and needed, i feel like it was still one of the best things about this drama. That being said, i still wish there was more of the survival part itself. I wonder how they survived with only water and candy and could still run around the forest like it was nothing. I also think that the progress on finding the bus and the missing people was a bit lazily done, and they could've done better. Acting was ok, but could have been better. Sakuraba Nanami did an alright job on her character but i personally found the main girl Konno acting like a goody two shoes all the time kind of off-putting. Yamashita Rio did the best out of all on portraying her character. The other characters and their actors were not too memorable. I'll probably look something else to watch from these actors though. Music was mediocre, but i feel like it didn't suit the drama. Overall i rate this drama 8/10, since the drama kept me entertained through the series and never left me bored. As for now, i don't see myself rewatching this drama, but i'll keep my eyes open. (Sorry for any bad english, i'm not a native speaker and this is my first review ever :--D)
