Not exploring Shino Aburame character well.
At his introduction, he seems like a calm, smart student with mysterious aura. Plus he has ability to manipulate insect at will.
What a interesting ability to be explored!
And imho, given that personality and ability, he can be another fan favorite character.
But no, they don't give him more screen time and cool action. Such a shame.
Imho, all team leader (Shino, Shikamaru, Neji) could get more screen time. Especially Shino.
He has potency to be more popular than some main characters if they give him more spotlights. They end up turn him into a bit "creepy" character.
Boruto even make it worse when they turn Shino into Iruka 2.0.
He lost his cool and mysterious aura.
