If you're looking for a sports anime like Haikyuu or Free or anything remotely realistic, this isn't it chief. Yes, it's about soccer, but everything you expect it to be about (comradery, teamwork, having fun...) isn't what Blue Lock is about. This makes Blue Lock refreshing in a way, but it's also why I'm putting this review as mixed instead of recommended - not everyone is going to like this subversion, and that's completely fair.
I myself, however, enjoyed Blue Lock - somehow it made me come back each week to see what the boys were up to. Yes, it's cheesy and some of the dialogue borders on cringy, but it was interesting to see what the hell they were going to come up with next to make our main protagonist seem like a genius. The animation is also great for the most part (I'm not talking about the less than stellar 3D, which they really don't use sparingly in matches), although I found the setting of this "Blue Lock" project to be lacking.
Overall Blue Lock is enjoyable for some, and a complete bore- or cringefest for others - I can see it go both ways. I'd say, if you aren't completely turned off by the idea of it not being your typical sports anime, give it a shot!
