Nozomanu Fushi no Boukensha

This shows started cool but quickly went down hill.
It is just : "Side quest, the anime" without any actual character development.

Our mc is a good guy so by doing these side quests he shows he is a good guy.
But wait !
With the next side quests, he shows yet again that he is a good guy.
Oh right and he is very overpowered but also modest to boot.

They completely forgot the fact that he has to sneak around because he is a monster.
Or completely forgot about the girl that buys him clothes in epi 1-2.
...
I constantly try to figure out, what is the point of this show?

If it was a show where he constantly evolved, gained skills, and show neat ways to use them or how they come in handy, that would be great.
But besides the fact that he can use 3 glowie powers combined into a MEGA GLOW ATTACK , I failed to see anything else that's note while.

Maybe develop the world and how he used to interact with it and now how it is when he is actually a monster that craves human blood.
They had that intent but quickly resolved it and moved on.
Apparently he only needs 1 drop of blood, so just a flash would last him 1 year or so.

At one point i paused and episode and forgot about it, after I went and started the next episode, i realized only later on that i skipped half of the previous episode. BCS IT IS NOT RELEVANT at all..

Overall rating 5 - Huge disappointment

Great premise and huge potential for a great story that quickly turns into garbage writing and kids show. 
It had a good base recipe for an interesting story: 
A good,hardworking, likeable adventurer who, despite all of his effort, cannot move past the limitations of his body.  gets killed and finds himself to become a monster while retaining seemingly intact consciousness, personality, and memories. All while having a mad scolar/mage/love interest who is willing to hide and help him stay human on the inside.

It had no isekai BS, no harem. No stupid, silly jokes, and good art to boot. 

It explores the themes of : The meaning of humanity, ... Struggle with his growing monster urges, Getting stronger, and overcoming the limitations of his human past self, Exploring fantasy world full of guilds, dungeons, monsters, kingdoms etc.

I watched up to ep 4 after which I went to read the Light Novel since usually it is better and provides more details and a better story since anime adaptations tend to change things to fit the anime format. So I know the full story in advance. 

After episode 4, the quality takes a nosedive, and it only gets worse from there. Remember the premise and all the major themes the show explores in the beginning? When you can forget it.
The show becomes extremely silly.
All the mature content gets removed. And by mature, I do not just mean blood, death, or sex.
I mean anything that an adult can enjoy. Complex and engaging story with twists and interesting and realistic human behavior. Good writing in general. 
All the philosophical, moral, and dark parts just cease to exist. The author will mention them  but will never actually show them. 
The story becomes a collection of filler episodes and scenes that push the same things over and over without showing us any new perspective on things or character development of any kind. 

The number of silly and stupid things in the later part is insane. It completely abandons the initial themes and turns into the adventures of your friendly neighbor, Spider-Man, I mean, vampire adventurer. Every Saturday at 10 a.m. at Fox Kids!

Boring!
Once again as it's common with this season it's starts off with an interesting and exciting concept, adventurer turned undead, can evolve by killing other monsters. That's quickly dropped after a couple of episodes, they then just focus on talking... Talking a d more talking. To summarize one episode, they start talking about the quest or introducing it for about 3-4 minutes, then they move on to the girls house to because she got to be updated on the upcoming quests, they talk again for minutes, then they head over to the village where once again he gets to talk to the people about ... the quest... The actual quests happens, 3 seconds of action, quest over and boring talk for another four minutes. Episode over. I think they run out of budget and are stretching 5 episodes into 12, because I'm 9 episodes in, there is 3 left and this season hasn't gone anywhere yet.
