It gets good and good, as the show progresses, season by season. Season 1 got a bit slow, but that was only because there were 4 episodes. Season 2 got interesting, and it concluded with an epic confrontation between the three heroes and Dracula! Season 3 was excellent. Up until the last episode, which had a pretty bleak conclusion, how they left it with each character; just when you see a glimmer of hope you get disappointed with the dark reminder of humanity!

Castlevania, while based on the popular video, to me is like Game of Thrones, but animated, and with vampires!
