While it does wither out a bit towards the end, Blue Lock has managed to entertain me for many, many weeks. Let me clear something up first off. DON'T WATCH THIS ANIME IF YOU WANT TO WATCH A GOOD SPORTS ANIME OR A GOOD ANIME ABOUT FOOTBALL. Ao Ashi is a brilliant one in that regard. I don't think this anime is even aiming to be a good sport anime. All it's trying to do is entertain the crap out of it's audience. And I think it has easily succeeded in doing that. That's why I can't even compare Blue Lock and Ao Ashi. Because both of them are aiming for very different things. And I think both of them are a success. From what I've read, the author was actually making a battle manga first, and then he changed his mind to make it about football. That alone tells you what I mean.
Now lets get back to Blue Lock. What makes this anime so fun? Well, other than the savage animation, character design and the exciting soundtrack, I think it's seeing how all these monstrous characters compete against each other, and seeing which one of them eventually comes out on top. The different innovative games of competition as well as the high stakes, reminds me a bit of animes like Tomodachi Game. And I actually couldn't predict a lot of directions that the story went on to take, which made it all the more exciting. While I agree that this anime has no specific structure and it's just one huge moment after the other, with hardly anytime to breathe or learn about the characters in the middle, I can't exactly complain about that because I got goosebumps in almost every one of those moments.
Another thing I really liked about this anime was how it sets up many little points across the story, which will going to come into play later. That just made the cliff-hangers after every episode even more exciting and you just never know when they are going to resolve that plot-point. Because of the patience of the anime, and the long build-up, when those moments finally happen, they are just perfect. Golden Kamuy was another anime that did this perfectly. And Blue Lock wouldn't have been this much of a success without it's characters because I liked almost all of them, and they all get a moment to shine. Especially Isagi who seemed like a generic protagonist initially, but I loved the direction they took with him.
But this show always puts me off whenever it starts explaining the logic behind it's football and it's characters (like the scenes with Ego starting to explain how realistic "that" moment of the match was and what was the logic behind it. Clearly, this anime is illogical, so those moments just don't work for me and makes me wonder if the anime isn't self aware.
