Meandered a bit at points, but think the ending was probably about as "good" as it could get for world/lore.
There's a big part of me that wonders how much better this would've been overall if the Sisters and Forgemasters were cut from the whole story entirely. The Carmilla fight was about the best they had to offer, with Strga's just kinda being a silly slaughter of farmers despite its attempts at spectacle as a poor man's Berserk. Isaac and Hector otherwise get treated like garbage throughout their lives and just decide "lol we're adults fk dat" in what feels like almost out of character shoveling of maturity at the viewer. Their collective influence in attempting to resurrect Dracula is otherwise minimal, which is probably the most wasteful aspect of setting up a potential generational conflict.
The trio probably had the better portion of this season's plot. Sypha remains OP and Alucard does his thing, but I'm rather disappointed in how they handled Trevor and the Death fight near its conclusion. A bunch of screaming, flaming close-ups to replace combat rather reflects the poor set up and choreography of the encounter. There's also no real reason why the others couldn't have joined him other than the teased set up he was going to die. But he didn't, and main to give SG a last minute redemption.
That said, I do feel like SG and the Illusory Corridoor had the most wasted potential. I know some of us speculated the woman he'd been chasing after was Shanoa as a possible bridge between entries/neat lore nod. Turns out it was just some random woman we never learned the name of and really couldn't come to care for. In the end, it just served as a way to wiggle Death into the plot and a minor component toward Dracula's revival. This could've otherwise been a major backdrop in an alternate telling of the tail, providing more varied locales for the heroes to traverse alongside presenting more diverse threats. Sure, it was fun playing "Who's that Pokemon?!" with some of the monsters that showed up, but a lot of the non-fodder wound up regrettably forgettable as either more obscure references or original designs.
Drac and Lisa actually reviving and no one really knowing about it now is probably the only real curveball thrown. Assuming a sequel series in the future, however, this still mandates something tipping Drac back toward evil. It's obvious Lisa would die of old age unless he turns her, but I don't see that being reason enough for him, nor would he likely do it (or she approve). Him going to England is otherwise a playful wink and nod to other aspects of myth linked to Dracula, but unless the citizenry there winds up murdering her, I just don't see him losing his shit again without significant outside interference. Then again, we can't rule out the possibility that Death isn't dead.
