Dr. Kenzou Tenma, an elite neurosurgeon recently engaged to his hospital director's daughter, is well on his way to ascending the hospital hierarchy. That is until one night, a seemingly small event changes Dr. Tenma's life forever. While preparing to perform surgery on someone, he gets a call from the hospital director telling him to switch patients and instead perform life-saving brain surgery on a famous performer. His fellow doctors, fiancée, and the hospital director applaud his accomplishment; but because of the switch, a poor immigrant worker is dead, causing Dr. Tenma to have a crisis of conscience.

So when a similar situation arises, Dr. Tenma stands his ground and chooses to perform surgery on the young boy Johan Liebert instead of the town's mayor. Unfortunately, this choice leads to serious ramifications for Dr. Tenma—losing his social standing being one of them. However, with the mysterious death of the director and two other doctors, Dr. Tenma's position is restored. With no evidence to convict him, he is released and goes on to attain the position of hospital director.

Nine years later when Dr. Tenma saves the life of a criminal, his past comes back to haunt him—once again, he comes face to face with the monster he operated on. He must now embark on a quest of pursuit to make amends for the havoc spread by the one he saved.

Monster plays out like a macabre game of cat and mouse in a world that is frighteningly similar to real life. Uncomfortable subjects such as coercive human conditioning and the psychology of the sociopath, morality issues regarding the origin of evil and the value of human life, are horrifyingly, yet engagingly, realized. The protagonist, Dr. Tenma, struggles to fix that which is so remorsefully broken in his world. Monster is a chilling tale rooted in reality, a far cry from the superpowers and supernatural forces found in more detached fantasy series.

Don't trust this review. Most viewers think this show is a masterpiece, thus by probability you will most likely think the same thing. I'm going to say some harsh things in this review, but even if you think my word is the gospel, you should still watch the first few episodes of the show. And remember, a 6 is not a bad score. I did not dislike this anime at all.

First, on to the good stuff. This has a premise where a man is punished for doing the right thing. It starts off excellently, following his torment and the bizarre chain of consequences following ...

Monster is an anime that has lofty aspirations and does not come close to fulfilling them. It starts out fairly exciting, but it turns into an endless menagerie of typical psychological anime bullshitting that pretends to be meaningful and significant, yet ultimately says patently obvious things and never imparts any meaning at all. I cannot stress strongly enough that from about episode 40 on this anime is horrendously slow (it is probably a 7-8 level for the first 24-26 episodes, which is why I kept watching, hoping it could somehow salvage itself).

The story is pretty interesting at first, and were this an anime that ended ...
