Netflix's Castlevania Reactions: 5 Things You Need To Know
1. The Plot
The whole series is based mainly on Castlevania III: Dracula's Curse, though there are some changes to account for the transfer from side-scrolling game to animated series, as well as the direction of the series itself, where the Church appears as more antagonistic than Dracula himself.
The first season very clearly serves as a prologue to season 2 (which has been confirmed for eight episodes), setting up the characters and the plot of the next season. It's relatively simplistic, overall, but then the Castlevania games were never overly-complex in their story. Most revolved around the same theme of Dracula coming back to life every now and then before one of the Belmonts showed up to (literally) whip his ass.
Everything of major importance is set up in the first two episodes, which is fine, because this leaves more room for the characters to develop without any plot points getting in the way. The series also does an excellent job of making Dracula a more relatable and tragic villain, something the video games never managed to do.
Expect this series to be largely character-driven, with the plot more of a tool to further their development.
