Now let me start by saying that i dont have much knowledge about the factory and govermental side of the story. They did an amazing job at explaining the crucial parts to the story so you dont get lost trying to find an answer. Comparing this to other (natural) disaster movies ive seen its quite realistic. I dont know much about how radiation and the factory worked since i am NOT a professional in the field of this stuff. So i cant go around criticizing any potential unrealism. Altho even if there are mistakes (of which i didnt notice any) it wont surprise me since ive seen a lot of (natural) disaster movies being criticized by professionals in the field of the disaster explaining the mistakes in the movie. So ill be talking bout how great of a MOVIE it is. Not how much it makes sence scientifically. To start off lets talk about the story. Perfect in every aspect. The chronological order was on point and the scenes were also portrayed very nicely so you wont get confused in the slightest. The acting was so surreal and heart wrenching. There was only ONE slight (potential) mistake i noticed. SPOILER ALERT (search for END OF SPOILER to continue reading)!!: At the end where he was waiting in the room full of explosives. At first he was struggeling to breathe because of the radiation but when the story got emotional he was suddenly able to breathe normally. Now i put potential before mistake because i dont know whether pain killers can cause your air ways to function properly after taking the pain killer. I have a feeling that pain killers dont affect your air ways so thats why i want to point this out. END OF SPOILER. Now the music. To put it simple; nothing wrong with it. The emotional music was perfect. Rewatch value has to be high up there. I wanna bet ill cry again after i watch this for the second time. Amazingly emotional movies just keep tugging at your heart strings like that. Now of course i recommend this movie. Its simply amazing. I dont often see (natural) disaster movies that have an extreme emotional side to it. They are often thrilling but this was both thrilling and emotional. At first it seems not too threatening but when you think about it it gets very scary real quick. This really doesnt have to be visually terrifying for it to scare you. Radiation is terrifying.
