Rich, I agree that not all Realart OS are bad, but I still can't say that I find any of them superior to the first release versions.
The 2 examples that you provide (House of Dracula and The Wolf Man) are interesting, because I think in both cases, the original OS wasn't very good to begin with. I always found the House of Dracula OS to be oddly cluttered, and the floating heads of Frankenstein and the Wolf Man seem especially awkward-looking to me, so I agree that the Realart version isn't necessarily inferior (although I'm not a big fan of the use of photographs for the various characters instead of their drawn likeness on the first release paper). Similarly, I never found the first release OS for The Wolf Man very interesting: the composition is weak and unbalanced, at least to my eyes (I'm fully aware how subjective such opinions are). Therefore I could see how the oddly surreal montage of the 1948 Realart version, which seems to echo Salvador Dali or Giorgio de Chirico, might be considered more appealing visually, although personally I find it wacky as can be.
In other words, to each his own. I'm certainly not trying to argue for my opinion to be the correct one.
