Excellent hijack movie, very well made and well scripted. The plot was based on actual events, though the beginning was a little slow but it ended up with great thrill and intensity. Honestly this is one of the best Korean movies that one wouldn't regret seeing at the cinema, what I like about the movie is its tightly packed without much long drag and unrelated sidelines, unlike a lot of overrated boring flicks flooded with fake reviews and ratings. The actors' were all well acted and the setups were decent. The only issue is the CGI of the planes isn't at the highest quality that looked kind of fake which can be a bit more realistic, and some of the CG shots were a little too fast, but those were only minor flaws that didn't affect the overall integrity.
