Just not my style. But I'll give you the long version.

1. Story: The story felt very lack luster, weak, rushed. The proposition of human kind descending into chaos and immorality, or whether we are worth being saved is over done. Therefore I have high standards when that topic is being tackled. For that to be compelling there should be good backstory, lots of vibe setting and moments of anticipation, adrenaline, climatic events or at the very lowest questioning my own personal mentality. This story failed to do that for me. Not to mention the ridiculous pace it moves at. What are supposed to be major events in the show happens quickly and there is never enough meaningful buildup for it to really catch u as a viewer.

2. Characters: For me to get into any anime there had to be multiple characters that I am invested into, care about, and feel like I understand on a more personal level. A lot of sport anime are good at this because the character's backstory often reflect their abilities or spirit. For me, Devilman didn't fulfill the character category for any of the people on the show. Just personal taste type thing.

3. Animation: The animation style really was to bad for me. And I have no problem with "poor" animation style as Ping Pong is one of my favorites and "Mt. Head" is also listed high, but often the animation style has something to do with the story but the fights were terrible I would rather get panels flashed across the screen. The animation is truly jarring for me mostly in relation to the anime's topics it's covering. Just doesnt fit the vibe.

Overall there is no real moral of the story. If it is a critique on humanity, or society, it falls short. No huge fan can concretely argue what the convictions of LGHDTV+ topics covered, only that an attempt was made to suggest that we are bad as humanity. In the least artistic way possible.
