Good overall, but I expected more. The first few episodes are great, because the story is completely unpredictable, and the viewer is thrown into this crazy story with twists and turns. Unfortunately, once the novelty wears off, it started to feel repetitive and I just wanted the second-half to be over. Maou is very plot-driven, and the majority of the entertainment as a viewer comes from the plot-twists, fast-pace and excitement. However, as soon as that starts to wear off, there's not much left. This is why I much prefer character-driven dramas rather than plot-driven. A good example of a character-driven drama is Juhan Shuttai. Aside from the villain, the characters in Maou are dull and uninteresting, all with very boring motives. The villain is great, and the ending is very satisfying and poetic however, so it's definitely still worth a watch. The acting is good for the most part, however Toma Ikuta is nothing special, and is out-acted by his peers in almost every scene, particularly Satoshi Ohno who is great. I don't like the term "overrated" because everyone has different opinions and tastes. If you like action, plot-twists and thrills this is for you. If you prefer character dramas and more interactions between characters and how they grow as people, then you'll find this boring. In my opinion, the best action thrillers manage to combine the two perfectly. However, Maou only has the "action" and not enough "character". Once you've seen it once, you've seen it all, so it did not hold up very well on rewatch. Still, I recommend it to watch once.
