It's really amazing, even if you don't Stan the new debutted boys (but you should in my opinion) you can really enjoy the movie, it's a really well balanced sci-fi movie which is based on a virus like in the real world. There are moments that can break your heart, some moments that you could not understand at all, cuz this is only the first part (FNC is prepared to have 7 parts of this story) , some really fun moments (btw the group is also really funny and softhearted). I really didn't expect so much from a group which hasn't ever veen in an actor's production, which aren't actors and are beginners, BUT OH MY GOD, they did so well. I really recomend this movie, if you stan them, even more, cuz it's connected to their debut!
Like their jump in the time it's all so logical, here is so much actions, so powerful but also educative moments...really, you should watch this masterpiece!
