After the trailer, I was really looking forward to the movie. But when I watched the movie, I had the impression of seeing a completely different movie. The trailer looked cool and like a good sci-fi movie. The movie then turned out to be totally silly. A movie basically consists of a story, not a string of scenes. If a screenwriter, and here there were two writers involved, doesn't know that, then he's not a good screenwriter and should look for something else to do.
The movie owes many of its good reviews to the well-known and popular actors. How would the audience judge the movie without these familiar faces? I know the actors of the protagonists from other movies and series and I regret to say that their performance was far below their potential. Kim Woo Bin in particular delivered an over-the-top, inappropriate, and very shallow performance. I was sad to see Kim Tae Ri in this nonsense.
If I wanted to list all the negative things I noticed in this movie, I would have to write a very thick book. But the movie is not worth that time! The film is not even worth the time you have to spend to watch it!
So I say to all those who have not seen it yet: Don't watch it! I can't recommend it!
Oh yes, and I will definitely not watch the second part, it would be a pity to waste the time!
