The reviews for this series have been quite polarising, and essentially you can separate based on one factor:
- Whether the viewer has ever played a sport competitively or not.
The drive for self-improvement, the need to win - Blue Lock as a series provides a multifaceted view of this idea via its main cast. If you have played a sport competitively (at any level really), then you'll be able to understand and empathise better with many of the characters. Unless you've experienced a competitive setting yourself, it'll be hard to really enjoy what makes each character tick and just write it off as unpalateable.
It really doesn't matter whether sports anime would "conceptually" make sense in real life either (see Kuroko no Basket, Hajime no Ippo, Haikyuu!, etc) because having anime as a medium itself allows for more flexibility for the entertainment of the viewers. It doesn't make sense for someone to tune into a sports anime just to make sure that everything is accurate to real world rules to a tee.
Personally, I like Blue Lock because it brings me nostalgia to those days and it's an easy watch that you don't have to think too deeply about. It's exciting, it's enjoyable seeing every character develop on both a "football" level and a personal level, and you really do end up waiting week-to-week in anticipation on what will happen next. In my opinion that's all you need in a series really.
It's fine if you find this series cringe, but having an inability to empathise with any of the characters just tells me you've never worked hard to try to be the best at something (which is fine, your life and all).
