Nine minutes about... nothing. That's an obvious filler, you're right. Sorry, can't do nothing about it, but it's still funny) And perfectly fulfills the role of chewing gum for the viewer without touching your thought processes: you chew it up and spit it out. It's not the one that'll make you pee with the boiling water, or even remember it, but surely the one that won't let you get bored
Kuroko's Basketball: Let's Chat is a nine minute DVD special that recaps part of season one, and the rest is random chaos played off as humor as the characters break the fourth wall and reference being in a "fan disc episode". Really, no one needs to see this. It doesn't even work as a full recap of season one because it's dropped after covering three matches, and the jokes based on characters' personalities have all been made before.
Every measure to save the animation budget has been taken, and whenever something interesting requiring a lot of movement is happening it's illustrated entirely through dialogue as we
get a still image of outside the restaurant they're in or talking floating heads moving around on a blue background. Even completionists don't need to bother with this one. If this is something made for the fans then it's in poor taste to make them something so lame.
So, I see that a lot of people don't really like these things, and I'm not sure why. I find them pretty funny.
What this episode is a comedic recap of the first season of Kuroko no Basket. Or it starts that way, at least. The Serin High basketball team (minus the first years other than Kagami and Kuroko) are at Maji Burger and they start talking about the matches that happened when Kiyoshi wasn't there.
It's supposed to be a funny little meta thing, but it isn't all about the recap. Eventually, it turns into craziness like Hyuuga's glasses being passed around and Kise,
Midorima, Momoi, and Aomine showing up.
Kise shows off his new photobook which is then thrown around and ruined by everyone because they get into a bit of a fight. It's good fun to watch the characters mess around, so if you're looking for a little laugh, maybe even something like the NG-shu things, than watch this. I liked it a lot.
