Considering someone with high iq you would think he can create a new more powerful shadow jutsu on his own. Or at the very least figure a way to be more efficient with his chakra used. But nope. He does his shadow jutsu only twice and he is done. Not even taijutsu can save him. What a waste of character. Here is an idea for the writers. Have him carry a gourd like Gaara but inside some dark matter that he can manipulate shadows from or pull people in. That would at least give him a buff.
