I realized that I was a teenager since I last read some comics. But Barefoot Gen is no colorful Mickey Mouse or Asterix. Not everything is right with the world at the end of the book. The story is painted in black strokes, the hardships of hunger and the cruelty of war, even before "the bomb". As this is part one in a series, this depicts Gen's life before and right when Little Boy exploded over Hiroshima in a very very moving way. And the cartoon form is no drawback, but simply a way to make it more real for the reader.
