People desperately wanting Naruto to be weaker since their favorite isn't as strong as him. I was that way once, but thank God that I outgrew that before I got on a blog.
People need to realize that you could have the strongest chakra in this manga, and still loose if you didn't have the skills to control it. It's part of Naruto and it will always be part of him until he dies. That makes it his power. All characters in the NV consider Kurama's chakra as part of Naruto's power which can only mean that Kishimoto, the writer, considers it his power.
The arguments that it's not his skill should have died off when he started to actively control it.
