Many people do comment on how the soundtrack isn't as good as the previous adaptations, and while I can agree partly, it's definitely also not the complete bore that people are making it out to be. The music in the second arc (29 to 52) greatly improves the dramatic flair. The tracks aren't as present, but on the whole, they complemented the animation pretty well. Also, every time Hyuga had the ball, they played a particular track that I'm in complete love with.
Other areas of contention include cutting dialogue content and a few scenes in order to fit the first 25 volumes of the manga in 52 episodes. For example, they had to cut Kanda out, the boxing dude who falls in love with Sanae. More importantly, the Boku ha Misaki Taro one shot which gave important character development to one of the main characters (Misaki) was also missing, which is a shame.
The other big issue with this series is the reuse of animation. I think I've noticed too many times where David Pro reused the animation, but I think I can forgive them for it, because those new animation pieces are frankly the best of the franchise yet. For the first time ever, the special shots look as good as they were in the manga.
Which brings me to another point. Tsubasa 2018 is the only adaptation that has been able to bring Takahashi's dynamic and intense art style into animation. Maybe Tsubasa doesn't have "fluid animation" all the time, but it gladly made up for it with a lot of really well-drawn shots. Even the stills that often match those in the manga look like there was a lot of effort put into them. You can pause the series at any point, and you will simply not find a lot of "QUALITY". It's just great to look at.
To be honest, I'm quite satisfied with this series. It doesn't have the super amazing soundtrack of the original or Road to 2002, but is it honestly that important especially when you consider the fact that Takahashi's vision (story and art) has been successfully transcribed to anime format? It's all there without the useless extra baggage of the other adaptations.
The final episode teases us for a future adaptation of the third and final arc of Captain Tsubasa which was sadly missing here. If it doesn't happen, it'll be the biggest blueball in anime history, especially after the last 2 failed remakes.
