To me the show felt lackluster as a whole, be it because of the linear nature of the characters or the unexciting art style.
The premise of the whole story is an interesting one and it's exploited in a smart way ( the never ending back and forth between light and whoever it's trying to catch him is developed in a charmingly convoluted way), but the watcher never feels threatened by the possible outcome of it since there's not much room to get attached to any character: they are very dull and feel like one trick ponies, not even mentioning how superficial their analysis is compared to the development of the plot.
The art direction definitely isn't enlightened either since, except for a pair of original moments (chips), nothing truly leaves astonished or utterly speechless. As the plot unravels this becomes a bigger and bigger problem because of how quickly the watcher gets accustomed to the initially interesting scenes in which names are written down on the note. 1st Op, ost and sound design are pretty cool though.
Overall, definitely not a masterpiece and hyped to the point of setting the watcher's bar higher than the show can reach.
