After watching trailer, I thought it was going to be an entertaining and different as it involves school but it had the same troops like other zombie movies.
Good points:
1. The production value is great. The scene where the students burst out of the windows while the girl was trying to commit suicide was highlight shot . Even during bomb blast thing, the zombies gathering was amazing.
2. The acting of all the actors were quite on point specially antagonist did a great job.

Bad points:
1. Why was it 12 episodes? It just dragged the whole show with unnecessary things added. The editing is to be blamed.
2. How can students turn into superman while fighting and even old firefighter father can do that kind flips? Moreover, the small baby survived without milk for that many days. Even the students had that much of energy without eating or drinking for days. That's so unrealistic.
3. There are countless number of stupid decisions that restricted from building up any emotion towards any of the character.
4. The emotion of friendship between teenagers looked so force from the beginning like On-Jo didn't even called out or searched for her best friend at the very beginning of zombie attack at cafeteria even after they got out of the vulnerable situation but she suddenly feels bad for her at the time when she was converting into zombie. Don't get that thing??
5. The sound track other than the theme song, is so bad. How can you play comic sound track in those intense scenes? And want us to feel the pain of the characters while being chased by zombies.

Disappointing!!
