Review of Monster

For gods sake, I never wrote a review, but this time I´m so upset that I´d really need to do it, in first place, monster has a big potential and I thought my expectations would be surpass, but it was the complete opposite,monster has little problems that start to acumulate and screw up the show, in the first 24 for episodes I was loving the anime, the mystery was engaging and I was curious to know what would happen, but after some time, when I thought the show would give more attention to johann, and develop him, showing us why he is so badass, butthat simply never happen, the last 35/40 episodes declined so much that I can´t even describe, when I was in the 60 I was really wanting to drop, they thrown away the main history and focus on secundary charachters that basically dont add anything relevant to the history, and when I say secundary charachters, its not five or ten secundary characters, it looks like a hundred, for real, ther are a lot of then that I cant count, I never saw a anime that has so many characters like monster, for real almost every episode they put a new one in the show, I really cant understand that, I was like in the episode 70 and they were still showing new charachters, why???? I simply cant understand why they cant focus in one thing, and what they want when putting so many episodes to fill gaps in this anime, if it has like 24 episodes it would be so much better, the way its executed is horrible, the main vilain is literally treated like a god and everytime called a monster by people who know him, he simply do what he want without any consequences but we never see that, he can manipulate every one that looks like magic, but monster never show to us how johann do what he do, we literally see him doing something the can be considerated cool 2 or 3 times in the entirelly show.
In generally, the characters are so empty, I can understand why tenma is how he is, but he is so boring and hypocrite that makes me angry, nina is literally schizophrenic and do not have a personality, you can say that this is ok because she dont have her memories, but she recover it pratically at the end of the anime, which makes the character empty, for real, a show with a hundred of different characters and I just liked two of then, that actually made me able to see the anime until the end, they are grimmer and lunge, the only good characters in the entire anime.
Well, I just want to express my indignation, I cant understand why this anime have 8.75 when it has so many problems, if you want to start monster, do it, but if you think it is becoming confuse and boring, drop it, it wont be better anytime in the rest of the show
