You watching the anime series? I only watched some episodes to cover for the manga volumes that are missing from the scanlations and it was indeed quite the chore, shit drags like crazy. Watching Ken and Rei slaughter random thugs gets kinda old after the first SEVERAL HUNDRED. Then the Toki rescue arc was all "THANK YOU KEN, BUT YOUR JESUS IS IN ANOTHER CASTLE". Goddamnit.
Anyway just read the manga, it aged a lot better than the show. And the new movies do a good job at animating the better parts of it.
