Dr. Frankenstein's Depravity
Perusing through the posts here, it seems I am not the only one who was a little put off by the Doctor's general depravity in this installment of the series. I much more prefer his character in the other films, which I would describe as detached and amoral, caring only about his pursuit of scientific discovery. Note I said "amoral" and not "immoral" - it isn't that he is evil, its just that he operates completely outside of the realm of morals. If something needs to be done to further his research, he does it without question, but he does not go out of his way to do evil.
In this film, he seems to have become more a of typical evil villain. The rape of the young doctor's wife is probably the most obvious example and totally out of character for him (in my opinion). But in general he just seemed more depraved and evil than usual.
I loved the movie anyway - its awfully hard not love these Hammer horror films - but definitely my least favorite version of Dr. Frankenstein so far (in the Hammer universe of films anyway).
