Always felt like I'm playing a video game rather than watching a movie 😂. All Sci-Fi movies are unrealistic, but Korean Sci-Fis often feel too childish and predictable. The graphics are great though 👍.
MILD SPOILER: Ends with a cliffhanger, but honestly the storyline could have been done in a single film. I don't feel like I'll lose anything by not watching the sequel (the way I felt waiting for endgame after infinity war).
I wish there was more logic to many of these Korean films. They've a lot of potential.
