The best Castlevania has offered yet, with intriguing, natural dialogue, great character development/exploration, and gorgeous action sequences. If you struggled the first two seasons, it's worth it for this.
Castlevania (Season 3)
Season 3 of Castlevania is more polished, has better pacing, and a more solid tone and vibe than the first two seasons. While I didn't get stabbed in the cry holes this time around, it's more grounded than the previous installments.
Castlevania (Seasons 1-2)
A gory, gruesome, and gorgeously animated piece that while slow in its start is powerfully emotional. I cried pretty good at the end.
