Wolfman's earlier TOMB OF DRACULA run is also highly acclaimed. But that series as well, along with Wolfman's other 1970's Marvel work, suffered from the deadpan stilted pseudo-Shakespearean Marvel style it conformed to.
Interesting point. Perhaps ToD is his most acclaimed work at Marvel precisely because the subject and character lend themselves to pseudo-Shakespearan style.
Yeah, the stilted dialogue is period-appropriate for Dracula (although the series is mostly set in the present, he is a centuries-old character.)
The other series I felt the Shakespearean dialogue worked was in THOR.
And DOCTOR STRANGE. Because again, it manifested ancient spells and occult mysticism.
But mostly, I felt it diminished Marvel. I got more interested in Marvel when that started to fade. One example, the Bruce Jones/Brent Anderson KA-ZAR run abandoned that type of dialogue, and was far better for it.
