Even if Hinata appears at any time, they never let her do anything. All she does is 'ano' + blush and then faints.
Naruto pretty much is a waste of all the good characters. Shikimaru, Kankuro, Temari, Hinata, Chouji and Kakashi. Although thankfully we get a lot of Kakashi.
And to a lesser extent, Ino, Lee, Guy, Tsunade, and most of the Jonin. Basically everyone except the characters that the story focuses on are good characters you want to watch more of, but they don't show because OMG SASUKE and the show is about Naruto and 'Team Kakashi'. aka Team Sasuke.
At least with Shippuuden, Sakura has become a pretty decent character. But I’d still rather see a show about Shikimaru, Hinata and Kankuro.
