Enjoyed But !! Something turned out missing.

Don't expect more !!!

I expected another best thriller from Director ' Lee Chang Hee ', Thriller/Mystery/ Action Webtoon adaptation + top casting currently trending combination, also casting like Choi Woo-shik and Son Suk for the plot. It started very well, from a person accidentally killed another person . Let's see what happens next, but after the fifth episode, it totally went down. Good screenplay, but messy story telling and narration sometimes confuse me. Once the schoolgirl suicide story starts, drama takes speed to run forward. I expected let's see what they would bring up in their next cases this time to define law and vigilantism equally or justify the perfect answer to law and vigilantism. But once this story ends, that's where drama starts with a lack of thrilling elements or next-case-setup aspects.

Plot Setup :-

For the crime thriller genre,'the crime cases are crucial to give a good outcome for the thriller experience, like why they killed, what's their motive, and most importantly, how the investigation develops from ep to ep by solving them and how they reached the killer, but in this drama they got weak cases, weak investigation setup, and I surprised how quickly they solved the cases. Yes, it's an 8-episode drama, but in that case, if they focus on big-case investigation by giving background on small cases, then it would be a good thriller.

A plot twist is a top darma/cine aspect that introduces some new element into a work of fiction that either radically changes the expected direction or outcome of the story, or sheds new and startling light on prior events in the plot or indicates the one's drama/movie ending, after watching slow pre climax eps I'm excited to watch which type of plot twist they planted, but once plot twist revealed, I didn't understand it's weak writing or weak plot.

Drama weak points :-

• Messy story telling/narration
• Less thriller elements
• rushed crime cases solving
• plot holes
• failed to create suspense

Drama Strong points :-

• Actors acting
• Son Suk, Choi Woo Shik characterization song
• Cinematography
• Screenplay

The writer failed to give a more thriller/tight script, and the director failed to bring the best output from the drama using thriller elements, but what I liked and what is the good point in this drama is Choi Woo Shik, Son Suk acting, and also in the last episode, Lee Hee Jun, a wonderful performance from these trio. Especially Son Suk, as a neglected child and a cop working for the law and justice, given his well-settled performance. Choi Woo Shik's characterization is a bit dissatisfying to me; in fact, he gave a decent performance as an ordinary student and a dark no-mask vigilante. But there is no strong characterization this time, or it's for me to expect more raw characterization from him in a thriller like The Witch. Once he justified his killings, there was no character development for him, and he became a side character in the last episodes. At this point the Writer and Director failed to utilise his potential fully. Yes, plot looks great but it only get hit when the writer polish the adaption more.

Direction and other Departments :-

I like the director's "Lee Chang Hee' works. I watched his previous works, "Stormer from Hell" and "The Vanished." Both are good crime thrillers. His taking clearly marks thrilling elements in those works, but when it comes to Killer Paradox, it looks like he failed this time, but in some episodes he showed his mark.

The background score is crucial for thriller mysteries; there are times when background music saved some scenes. It’s important to add the right sounds and music in the background of suspenseful scenes to avoid confusing the viewer but except in some eps there's no right moment of background score.
Cinematography is good, especially some slow motion shots are excellent !!

As a thriller lover I enjoyed but not completely ! ! !

I expected more...

After I saw the casting and the trailer I was really excited to watch this show and thought it would be another thriller masterpiece. However, it turned out for me to be a bit disappointed. It's definitely not a bad show and I still enjoyed it overall but I just couldn't help feeling sad that I didn't like watching it as much as I thought I would.

The acting and casting is on another level with Choi Woo-sik and Son Sukku as the main characters. Nevertheless, I wished for more screentime of Lee Tang (played by Choi Woo-shik) because I personally thought the thriller was going to be a bit more through the eyes of the killer than the police officer. Because of the lack of screentime I found it difficult to relate to the character or at least understand his traits a bit more.

The first episodes were all great and I couldn't wait to watch the show further but later on at approximately episode 5 and following I got a bit bored and it felt really slow. I personally didn't like the adding of Song Chon as a character but I do understand that he had to be there to make the story clearer. I simply wished for more thriller aspects. However, the ending really got me and I'm hoping for season 2!!!

(I did this review only based on the series I did not read the webnovel it's based on)

All in all, the drama disappointed me even though it may have been because of my high expectations.
