Yeah, while Castlevania 1 and 2 were great at the time, I would never ask anyone to play them now. I would tell people to start on the third game and go from there.
As for the series I just finished episode 5 of S2, will watch the rest tonight. I appreciate the world building and character motivations from Dracula's side. I like that he is so broken that nothing matters except the end goal. There is no fire in him, only the end matters. The "fucks" and stupid humor need to go; it is always jarring when it happens. Godbrand's voice actor is the only one who sounded like a Saturday morning cartoon character, the rest of the crew are great. The animation quality is still sketchy but good enough overall to not be a major issue. I did actually freeze the screen once out of horror when Isaac and Hector are talking on their walk when they come across a fox. Go back and pause that exact scene and it makes you wonder if it was something added in after they already ran out of money.
