Our Review

Written by AnimeReview Team
Okay, buckle up, anime lovers, because I'm about to gush about an absolute masterpiece: *Monster*! I swear, this anime burrowed into my soul and hasn't left since. From the very first episode, I was completely hooked on this dark, twisting narrative.

The story, oh my god, the story! It’s a slow burn, a masterclass in suspense. Dr. Tenma's moral dilemma—saving a child over a powerful figure—felt so real and impactful. I was on the edge of my seat as I watched his life unravel, then completely rebuilt on a foundation of lies and hidden horrors. And Johan Liebert? What a terrifyingly captivating villain. The way his presence just oozes manipulation and pure, unadulterated evil gave me chills! I was constantly questioning everything and everyone, trying to figure out the truth behind Johan's existence. I felt so emotionally invested in Dr. Tenma's journey to atone for his actions, even though I understood his original decision. He's such a complex character, driven by a strong moral compass, and I couldn't help but root for him.

Visually, *Monster* is a work of art. Madhouse did an incredible job! The animation style perfectly complements the dark and gritty tone of the story. It's not flashy or over-the-top, but rather grounded and realistic, which makes the suspense that much more effective. The character designs are unique and memorable, and the backgrounds are richly detailed. As for the sound? The soundtrack is hauntingly beautiful, perfectly capturing the somber mood of the anime. The voice acting, both in Japanese and English, is phenomenal! Each character's voice perfectly embodies their personality and adds another layer of depth to their performance.

Overall, *Monster* isn't just an anime; it's an experience. It's a thought-provoking, emotionally charged thriller that will stay with you long after the credits roll. I absolutely loved the intricate plot, the well-developed characters, and the stunning animation and sound. This anime is a must-watch for anyone who appreciates a good mystery with some serious depth and suspense. Seriously, go watch it now! You won’t regret it.

As someone who read the manga years ago, the anime adaptation really nails the atmosphere. Johan is even creepier in motion!
