I think it's badass and i like Boruto. I also would like Boruto to eventually have the Tenseigan, because as Main Character it would guarantee we'd get some good development on it (rather than the almost criminally little info in The Last).

So far it seems the main reasoning is what Sharingan91 said: It's design is similar (blueish, glowing) and it can't be any of the other known eyes.

But as i've pointed out: it hardly is on the level of a Byakugan, let alone a Tenseigan.
