Imagine all the characters that you loved or had a crush on, you are suddenly a part of their world! That's the biggest attraction of W. Among some of the best elements that W presents to the audience are a very creative plot, with shocking twists and turns, often not foreseen developments and certainly a constant pull and push between anticipation and relief. Traveling to a new world or a new dimension is nothing new but the introduction of cartoons renders it a touch of incredible and humor at the beginning and once love steps in, the story takes a poignant turn. The story not only weaves fabric of fiction with reality but also projects a sense of wonder and mystery. It has both an old-school and a new-world charm to it. Somewhere in between, it does get complicated, but riding it to the end is the best thing you can do because when it finishes, the actual haunting begins. That's the best part. It's going to stay with you. The visual allures are incredible and the transitions remind me of Sherlock. Very fresh and quite unforgettable. I do have my complaints but none of those have actually deterred me from finishing the drama or dropping it. A dreamy hot Kang Chul and a girl-next-door Oh Yeon-joo who doesn't transform because of the plot but is rendered beautiful in the minds of the audience because of the change in perspective of the male lead and his growing emotions towards her is an example of the audience being conditioned by Kang Chul. The constant reminder of a fictionalized reality in the form of "TBC" appearing out of thin air and the panning of the camera makes it all the more exciting. The second best part is however, the awesome explanations and hypotheses discovered and challenged by the characters and detailed by the writer to determine rules and variables that drive the two worlds. This is one drama that you have to watch simply to experience suspense and major fluff :)

Being a writer myself, my sympathy with Kang Chul and his world goes deeper. For what if one of my characters asks the same question as Chul does- Dropping a character for the sake of a plot or simply on whim, and counting it as not murder but creative difference or even worse, artistic whim? How and to what extent can an author consider himself God? The monster reference takes me to Shelley's Frankenstein wherein the creation destroys the creator. Hands down, one of the best questions on existentialism put forward by a talented writer. Also, let us not forget hidden messages such as "moving on versus moving forward", "individual versus the world", "selfish god versus helpless human", "Man's chosen purpose versus Man's fate". It's a great replica of reality. Think about it, people who lose confidence or purpose in life, cease to live or exist, often choosing to become rather self-destructive...

I am hereby listing pros and cons as per my experience :-

Pros:-
Chemistry between the lead
Commendable balance between comedy and tragedy
The touch of incredulous in the story
Constant nail-biting action
Surprising plot twists
Graphics and 3d Rendering
Less nagging support roles
Quirky dialogues and interactions between the main characters
Good music and locations

Cons:-
Slightly exhausting story line due to complicated twists
Female lead starts as a super strong modifier to the plot but eventually turns into a princess-in-distress
Wasting side/support characterization on fillers
Uninspired actions of the killer
Questions deliberately left unanswered

W is not a flawless drama. But not giving it a go will probably make a dent in your world. So, give it a chance :)
