As the premise states, the plot is pretty straightforward. Sengawa is our anti-hero that is by day a clumsy, unsuspecting police accountant, and by night he is an assassin for hire that takes on jobs to deliver his own form of vigilante justice. This actually kind of interesting—and it is, for the first fifteen or so chapters. But the overarching plot itself is not actually addressed until much later in the course of the manga. At the very least, this does not distract from the enjoyment of watching our douchebag villains get knocked off in the most elaborate and gruesome of ways. Yet while there is satisfaction to be had through that, the plot is simply cut and dry. If I'm sounding repetitive by saying that, then I'm doing a good job of echoing the form of Dendrobates' plot.
That said, in the realm of characters—it does have some likeable characters. Most of them don't live very long, outside Sengawa and a few other policemen. Development, given the plot, is incredibly minimal. Arguably, it does not exist at all. From the onset, Sengawa is a murderer with something of a conscience. He seeks to right wrongs, to dispense justice where the justice system itself cannot or would not do so adequately enough. By the end, he's largely in the same position he started off in. And none of our other characters get much exploration themselves.
The art is perhaps the strongest point. It is clean, clear, and detailed. It's part of what makes this manga so easy to pick up and read. The frames are actually structured pretty flawlessly to help you follow along with all of the action scenes.
Ultimately, Dendrobates' biggest problem is development and character exploration. It's shallow, it's dry. It's like eating a snack rather than a meal—for a brief moment it is enjoyable, but it won't sit with you in the long run.
