Monster
Honestly been a while since I've watched it but I remember it was thrilling, with Dr tenma being one of my favourite characters ever.
The mystery was thrilling although it was a bit predictable.
The climax and arc leading up to it was 10/10
After the start where he just got on the run and before the perfect climax there was a point in-between the charming interactions with other characters that was a bit slow, especially the excess amount of flashbacks.
