I've watched 7 episodes so far, and I have to say that Orion has taken a firm approach with the story and characters that was missing in Ares. I'm reviewing this show as a 20-year old dude who has been watching Inazuma Eleven for 8 years.
The story is much better; there is the usual scary organization behind the scenes that uses middle schoolers to take over the world or something. However, the team's response is finally worthwhile. Kidou gives no shits about the wholesome soccer spirit and actually fights back. Episode 6 in particular was so enjoyable because finally they decided to beat up their
enemies instead of the other way around. It was really funny to see the trope being reversed, and I laughed so hard in that episode
I also really like the progression of power in Orion so far. Goenji is as hype as I wanted, and his plays removed the stale taste from Ares. It's also great that Inazuma Japan is actually evenly matched with the other Asian teams, and they have to rely on beating the other teams' gimmicks rather than just getting powerups through the course of the match. I'm glad that they stopped the whole V2, V3, G2, G3 system and simply use hissatsu tactics, shoots and goalie moves. Endou's power up is great too, and doesn't feel forced. The team already has incredibly strong hissatsus like The Explosion, Perfect Penguins, so they can contend with the Asian teams while still developing even stronger ones that are world-level instead of Asia level.
Art is really good at times and acceptable most of the time. Kinda sad that it sometimes isn't as pretty. Music is awesome and gets me hyped.
Characters look good for now. Ichihoshi definitely will get a character development arc soon, and Kidou as usual is the best character of the series. Kidou, Gouenji, and Endou easily made Orion better than Ares, but so far Endou hasn't had as much impact as Kidou, Haizaki, Hiroto, and Gouenji. I'm looking forward to Nosaka coming back as he was the best character of Ares.
Overall I'm giving it a 9 because the show has broken some old annoying tropes, has paced itself well, and has a solid plot progression.
Story 6/10 :
Again a new system comes as always, but this time it is a bit too much. They included all the old characters and now kicking them out one by one. The FFI was also in the main first season, but this time too awkard.
Art 4/10 :
Well I don't know they are sort of time or money on the animation, but it is just worsening after each episode, definitionely not expected from animes such a shit animation.
Just as Inazuma franchise, 1 or 2 traitors are always there, they aren't developing much, except Endou and Inamori, all have accepted the traitor but just can't
kick him out, and they hit him in Australia, yet he is in perfect condition.
Enjoyment 8/10 :
As I like Inazuma franchise from since I was small, I still enjoy this anime as Endou and Gouenji are there.
Overall 7/10 :
It is somewhat decent series, but animation is worsening, might be worth watching once. If planning to watch one, watch the previous season first.
