I have rated it 5,5, because i have high expectation. I am not comparing this with other k-dramas or asian dramas. I am comparing this with american productions or japanese tv serial. The story itself is ridiculous. It is a fantasy, i get it, but the logic in this drama is so below expectation that i feel the writer was treating me like an idiot to watch this. The rules keep changing. Like can go back and forth between two worlds but how? Sometimes tru tablet sometimes just go in and out like that. Then killer can go in and out anytime he likes without tablet, But when tablet is not working it's safe, killer cannot go out anymore. Sometimes can go to airplanes too. What the hell? Is it me who fails to understand the logic behind this utterfly crap master piece or everyone also feels the same? Don't even start to talk about the awkward romance. It's the most ridiculously cheap cheesy romance i have ever seen in my entire life. Or maybe i haven't found other idiot drama as comparisson. I don't know. I have high standard for movie / anime / tv show, this one is the most overrated drama so far. I watched it because of the hype. Ahh i won't ever trust the hype anymore. Wasted my time to watch this. I feel like getting cheated by the seller (writer). The sales person tried to sell me a fruit with nice packaging, promising sweet taste. The first bite was good, really sweet and tasty only to discover after i bite more the fruit is rotten inside with all the worms squirming inside of the fruit. Yuck! That's how i feel when i watch W. Such a letdown. What a BIGGEST DISAPPOINTMENT !!!
