This is my first time writing a review lol, so bear with me + this is all MY OPINION :)
To be honest, these other reviews calling blue lock trash are quite confusing and a bit tasteless. I mean compared to other sports anime, Blue lock takes a different approach and brings something new to the Table, like and anime that is based only on strikers is quite cool. Yeah some people may say oh why is it only focused on that, without watching the rest, but along the story we do see the importance of other positions on the team, so that is a new approach.
For something to be interesting it doesn't always have to be complex, sometimes simple and straightforward storylines like the one Blue lock has is all we need.
Regardless of its flaws or what people say, I am very much enjoying this, and this is coming from someone who plays sports (soccer included).
In conclusion Blue Lock is cool, so give it a try lol.
