The Blu-Ray was the cost of the rental stream from Amazon so physical media won. I watched it as part of a two-day Argento triple feature sandwiched between his The Phantom of the Opera (with Julian Sands, not to be confused with the 1987 Fraticelli and Argento giallo Opera) and a local arthouse screening tonight of Four Flies on Grey Velvet. I hadn't seen any of these and decided that I might as well make a feast of it.
So, Dario Argento's Dracula.
The gratuitous female nudity is indeed early, and gratuitous, and repeated occasionally but not constantly. Nudity aside, it's less misogynistic than I have found several of Argento's films to be.
Didn't watch it in 3D so I can't remark as to the "things flying at the screen" portion of the review.
Harker comes to work for the Count as a librarian, which I believe means someone involved with the script read Kostova's The Historian.
Giovanni Franzoni as Renfield reminds me of Beef in Phantom of the Paradise.
Thomas Kretschmann, interestingly, plays Dracula here, but plays Van Helsing in the current television series Dracula starring Jonathan Rhys Myers.
Dracula sees and hears through, or is, rats, flies, big beetles. He also takes the form of a wolf, an owl, a swirling cloud of black dust, and a giant mantis 8-10' long, perhaps only a bit smaller than the giant ants in THEM!
I don't remember a bat, but there's a lot going on here.
Rutger Hauer as Van Helsing is a bit quieter in the role than I might have thought. He does not appear until late, but then has a great deal of screen time.
Lots of theremin in the score, as gratuitous as the nudity.
To sum up, camp.
