The things about vampires, "mother earth," having superpowers, dances with dragons, etc. is that it's their literal autistic fantasy world, not paganism. They want real life to be like LOTR (completely ignoring the Christianity/Catholicism of Tolkien's writings), Buffy, Harry Potter, or some other shit they read, watched, or played.
The thing about Vodou is that family is the foundation of society and religion, and they don't mean "family" in the sense of anarcho-kweer socialist radi-decon poly family. Even with the support for kweers and whores that they claim Vodou has it comes with a lot of responsibility, and everyone knows responsibility is anathema to them.
This is where you get into the split of Neopagan vs. Reconstructionist pagan -- or at least how it used to be framed 2000-2010s, especially by Recons(tructionists) who didn't care about the feelz of the fluffy bunnies as they were called in that era. The Neos tended to be this kind of glorified whatever goes fantasy that made them feel special that you see lampooned in the Neopagans thread in Community Watch, and are a lot more publicly visible.
The Recons were a much smaller collection of groups (Asatru, Hellenists, and a scattering of much smaller ethnically-oriented sects that tended not to really have settled names), and a lot more insular, especially as negative attention and conflation with muh white supremacy kicked up around 2010 against the Asatruar in particular thanks to retards in prison gangs. So they were always a lot harder to find, whatever the historical tradition they were trying to reconstruct and practice. These guys tended to be a lot more willing to dig into historical sources (some ended up becoming professional anthropologists or historians) and embraced the responsibility angle you mention. They tended to burn out after 5-10 years of practice if they didn't have a larger community of practitioners to be embedded in, like the Rodnovery and Romuva guys in Eastern Europe sometimes have available.
My impression was it was a combination of not having that broader community support reinforcing the belief and ritual, and helping to spread around the responsibilities, and also just the pressure of the larger, secular culture. When you're living in the modern, scientific world, the mismatch between transplanting a 500+ year old belief system into the modern day eventually gets to be too much, and it breaks down. Some of these guys abandoned whatever it was they'd adopted wholesale, others retreated to the "it's poetry/symbolism but not literal" stance and kept a form of it as a personal philosophy, but were otherwise atheist.
The other factor in why I don't think you see many Recons these days, only the LARP/fantasy Neopagans, is the broader pagan community got hit *hard* by the social justice/critical race theory plague earlier than some mainstream religious movements. You can imagine how destructive that shit is when dropped in the middle of a group of people with oftentimes mixed European ancestries who are far removed in time and geography from the religions they're trying to adapt and practice. The folkish (ethnic origin matters, everything is by default a closed practice) pagans were at the throats of those with insufficiently-pure ancestries, while others tied themselves into insane knots over whether or not they were <too wrong race> to worship <xyz gods>. It didn't take long before the usual social justice purity spirals blew up/burned out most of the Recon movements I saw in that era, and it did it *fast*, almost as fast as it wiped out the New Atheists.
So, now all that's left, at least aboveground, is the kooky LARPing kids who use gods/myths/ancient cultures as fashion accessories, and come up with the weirdest shit that would've gotten them laughed out of even your average Wiccan coven around 2005. But shit's still lame, a lot of people still want numinous, mystic experiences, and the chase after the dragon of Reenchantment goes on...
