This movie was pushed on yahoo and its "news" source affiliates hard- so it "flopping" is indeed a failure of "the current age" - it was pushed and praised in articles as things such as "Somehow better than the source material!", "True to the source materials real intentions" and "While true to the source material, it is its own kind of horror monster movie, showing the unique animal side of Dracula!" the most "unique" part I got out of those reviews was that it showed drac weak and increaseing in power as he fed/killed... this somehow was, new? because they made him...more animal and demon like? I mean did they miss the demon-dog-wolf-style part? That part is nothing new for Dracula lore, Bram and expanded...heck even in Castlevania.
I mean, it was such a daring and brave part of the book, in all Bram based Dracula movies etc. it is, like...a scene that is used merely to build suspense. "Why is everyone dead? oh well unload AND DELIVER the boxes yo, union rules, hup hup!"
So sure, it is a good choice to base something off of, as there is room - but your start and end are set... so you either get something good that leans into the source material and uses that to make something great... or you do whatever you want because cool and end up with GoT S8 where you have to end at a spot that you really never aligned with.
edit: underrated dracula movie? Dracula Untold, come at me. Sad there was no follow up as it end capped it into Mina+Drac in the latter half of Stroker's setting (and had a setup similar to Castlevania Lord of Shadows 2 w/ death in a way)
