The Korean movie industry has been producing good movies all year round and Pandora is not an exception. Quality-wise you can't criticize this movie. They didn't hold back from showing what radiation can do to the human body and the desperation with which people try to escape this fate in a nuclear disaster. Thanks to the actors and actresses, that I am sadly not familiar with, the movie came to life and was believable.
However, even though I am not an expert on nuclear power plants, I couldn't help but be sceptical in some scenes. For example if the radiation is that high and the people were clearly on site where the power plant is, then shouldn't they immediately die from the exposure? In these scenes they could have pushed the image of "horror" involving this disaster more. What irresponsible people worked there when they just ignore leakage and other important stuff? It kinda seemed unrealistic to me that they handled the issue of a power plant exploding this lightly.
On another note, I liked how they focused on the different point of views from governmental authorities and residents to workers and Jaehyeok instead of solely settling on a heroic position and telling a story through just one perspective. Even though "Pandora" didn't keep me on my toes for approximately the first half of the movie or more (due to slow progress) they managed to get me afterwards as slowly everything went down the hill. I know they intentionally wanted to make the viewers emotional with sacrificing someone but I gladly accepted this emotional rollercoaster at the end since the acting convinced me that much.
Last but not least can! I! get! an! amen! Their critical approach towards Korea's current political situation and the usage of power plants definitely receives some plus points. When directors use their platform right to bring a message across to the audience it's always admirable.
