I'll cut this short. Castlevania is only 4 episodes due to it being the prequel to the actual show, Season 2 will feature 8 episodes based on Castlevania 3. Adi Shankar might have questionable taste in makeup, but his work ethic is incredible. Every person working on Castlevania was made to play Castlevania 3 on an NES from Ebay. This show wasn't made to rake in dollars, its first and primary concern is to make it into a goddamn masterpiece and while its not finished so I really should be more responsible with the way I'm rating it, from what I've seen I'm damn impressed. The animation quality is incredible, above most Japanese anime which this show clearly mimmicks. Voice acting is perfect across the board, the action is visceral and gory, but not mindless. The story and its pacing is unique and doesn't pick up on many generic tropes. It's a unique prequel to what is yet to come.
This show is for adults, its almost objectively the best western "anime" (Korra was primarily animated by a Korean studio, that said I'd still rate this higher) and unless you like good bad movies enough, its the best video game adaptation I've ever seen.
Honestly I haven't felt hyped for anything for possibly a decade now, I've learned that hype results in nothing, but considering the directors work ethic, his past work, experience and what Castlevania is right now, I can't feel anything but hype.
