Lost+Brain is a manga that had plenty of potential to be great. Unfortunately for us readers, it fell short, very short.

(Note: TLDR at bottom)

The synopsis of the story by itself tells you how it should be written. The manga should revolve around the plot. The plot should be intricate and riveting enough to keep the readers glued to the manga. Personally, I was glued to it, for about the first two chapters.

The idea behind the manga was pretty interesting. The use of hypnosis for control is, quite honestly, fairly creative. While some people do cry "herp derp death note ripoff herp derp", the concepts of hypnosis and the ability to kill anyone if you know their face and name are extremely different. The means which the protagonists use to change the world can easily be morphed into amazing storylines.

You are probably wondering at this point, "what the hell does this tell me about the rating", and I'm about to tell you. Where Death Note prevailed and Lost+Brain failed was the length. When reading Lost+Brain, you get the feeling that everything is moving way too quickly. The pacing of Ren's goal to change the world proceeds too fast for the readers. The way the manga goes about makes it seem too easy. It feels like checking plot items off a list instead of masterfully weaving things together.

While the ideas behind the story were good, the way those ideas were written down were bad. Everything felt cluttered and amateurish. It really is somewhat depressing to see a potentially strong manga fall flat on it's face like this.

TLDR: The plot had tons of potential, but the story was too rushed to be a strong manga. Hence a 3
