I'm gonna say it and i'm gonna say it now: KnB is the most predictable, shounen-like and overrated anime i have ever seen. We all know why it's rated so high: it is very enjoyable and flashy. It's like a weak version of Bleach, with more cliches and totally unjustified powers, since we're talking about basketball, not shinigamis.
The reason KnB is so popular is that it tricks the audience by creating false tension: you're there like "OMG this is so close, i don't know who will win" but actually know who's gonna win (Spoiler, but no spoiler).
And this brings us to my next problem: EVERY GAME IS THE SAME, and i'm not even exagerrating. Seirin always has to play from behind and somehow win in the last second by 1 point, obviously dunked by our MVP Kagami. Guess what, you stupid writers: COMEBACKS LIKE THAT DON'T HAPPEN EVERY SINGLE TIME.
This anime doesn't even try to accurately depict basketball. It ignores a lot of aspects. Fouls only happen when the plot calls it and nobody ever misses a shot unless the enemy planned it all along. If somehow they do miss the shot, it is just to showcase a rebound battle (they don't even show the shooter). And don't even get me started on the powers. People told me that these things are entirely possible. I call it bullshit. Only NBA players can do stuff like that, if they're lucky. We're talking about japanese high-school students for god's sake!
Story: 5/10
I couldn't care less about the whole Teiko backstory and even less about the games, since i knew all along who's gonna win. It's not something new at all, just about a team that wants to become the best in Japan. Why am i even talking about this?
Characters: 5/10
You might find them enjoyable, but they completely lack any depth and are very one-dimensional: the ambitious red-head, the silent guy, the other silent guy, the four-eyes and the gentle giant. Most of them aren't worth mentioning, since the whole anime is about Kagami and Kuroko. I also have a huge problem with the "bad guys". Yeah, i called them bad guys, because every enemy of Seirin is depicted as a deuchebag that hates basketball and bullies his teammates. It tries to make you feel that it's right for Seirin to win, which is a really cheap trick if you ask me.
Sound and animtion: 10/10
This is where Knb slightly redeems itself. I cannot argue that the OST is amazing and fitting for this type of show, and all those flashy moves are animated very beautifully.
Enjoyment: 7/10
Despite all the flaws, i did enjoy KnB while hardly trying to turn off my brain as much as possible. It is an anime for everyone and everyone should enjoy it as a mindless piece of fun.
Overall: 6/10
KnB, even though it had a lot of potential, fails miserably at being a sports anime and ends up being a generic battle shounen in disguise. Its presentation makes up for the lack of depth and realism, making it a somewhat enjoyable anime (that is, if you really try not to pay attention to details).
