**** yeah.
First 2 episodes are slow as hell, and even after that there's never any real climax to anything, but it's just crammed full of quality and building to a huge ****ing explosion that destroys New York - which Hiro saw when he accidentally went 5 weeks into the future.
And Hiro is my favourite character in anything. Ever.
He's got the best powers, the best drive, the best attitude and he's the only one who takes notice of the other super-people he meets (aside from the bad guys). All the other super-people inter-twine as part of some big plan, but Hiro's the only one who sits and goes "Hey, you can fly! Cool. I'm Hiro - I can warp space and time."
Plus he's basically the viewer. He hears about future-Hiro having a sword and spends a whole scene making lightsaber noises. And one time he stops time to stop some people getting hurt and as he walks up to move them he sighs and says in Japanese "Why couldn't I have super-strength too...."
