As I have come to watch more and more anime, I have also come to identify characters more by their voices than their appearance. This may be because, although animation is getting better and better all the time, it is still impossible to capture the infinite tiny nuances of expression that constantly play across the human face. [Afterthought: My voice-recognition may also be due to me having a hard time keeping up with many of the Japanese character names. I remember especially having trouble keeping up with the names in Ghost in the Shell.] It is possible to portray certain expressions, but the attempts are still crude at best, when compared to a real human face on film. HOS is quite cartoonish, although I am still impressed at the overall atmosphere of HOS. The HU Victoria has a much more pronounced anime-ish face: oval, very pointed chin, huge eyes. But of course, in my opinion, the eyes are where most human facial expressions occur. Don't you think? I think, perhaps, the disproportionately large eyes give the animators an edge in portraying facial expressions. HU Victoria seems much more expressive and more business-like; not quite so "Saturday-morning-cartoonish."
I mentioned before that I have come to strongly identify anime (and other cartoon) characters by their voices. Fortunately, all the voice actors are the same between the two series. This may not be so important for the other characters, but I would have been terribly disappointed to hear anyone other than Crispin Freeman's voice as Alucard. He just nails it.
This has been your pointless post for the day.
