(Note: This is a spoiler-free review of the first six episodes of Castlevania Season 2, however there will be spoilers for Season 1)
The first season of Castlevania was a surprise that I’m not sure many people were expecting. It was a solid, albeit it short, four-episode season that did everything you would expect from a Castlevania animated series. There were dozens of monsters that needed to be killed, a Belmont, and a pissed of Dracula that wanted to exterminate all human life. Still, it’s short length really hampered any enthusiasm I had for the season. Just as things were started to get good, the season was over. It felt more like a proof of concept than anything else.
Thankfully, we have a second season that gives us eight episodes and expands the story way more than the first season. If the first season was all about action and grizzly entertainment, then season two is more determined to get across the plot and character motivations. Unfortunately, this approach means that the series never hits the same high points in action as the first, though makes up for it with a deeper examination of Dracula, his cause, and his chosen allies.
