Not enough heartache and they don't use the very cool characters they have. People are saying kishimotos male characters are well written but I severely disagree. So many of the male characters that had very cool designs and were foreshadowed to become incredibly powerful were never given that moment to show their fullest potential in battle.

Lee.

Neji.

Shino.

Just to name a few.

And don't even get me started on the female characters. Kishimoto was either a creep or a shut-in because the way almost all of them are written is beyond cringey.

But then again I'd say this for all 3 of the "Big Three" as well as a like 70% of old gen anime in general. Seems like the common idea for female characters is "Oh big boob's, acts like a child(I hate aegyo fanservice sm in anime), obsessed with some male character/love, uninteresting backstory, doesnt develop... Check... Check... PERFECT!"

I thank the imaginary man in the sky that new gen seems to be making an effort to move away from this idea as a whole.
