So good. I watched the whole first season in one day. But I also see lots of flaws.
The most important flaw is the lack of bright elements. Continuous dark things are shown to us one after another which drowns us. Even the scenes that seem to be bright are, in fact, dark because they show hypocrisy in the background. The colors are always dark and gloomy, most conversations are full of lies, and hypocrisy, selfishness, spite, hate, greed, and evil are given to us without breath. This rate is like 10% bright to 90% dark in the series and over time it drowns the brain. Such series should be at least 70% dark, 30% bright, or 60 to 40 is the best. In bright elements, colors need to be vivid and clear, and they should have something that makes us laugh; romantic, fun, childlike stuffs are needed. Also, balloons, festivals, dances, friendship, relatives... the nature, butterflies, the greens, the smell of the wet earth, the bounce of the blue water...
