Well, that's the whole point. The 'hero' always comes out on top. It's a recurring theme in action series. The main character meets a strong foe and on occasions, find him/herself on the brink of death; someone they come in contact with some power that helps them overcome and then they move on to the next enemy, only to get even stronger.
Last series I completed was Fate/stay night. It was the hype about the movie, Unlimited Blade Works, that prompted me to watch it. It was, sort of, interesting. Though, I feel it could have been broadened. The movie was good. The animation was top-notch.
