I personally don't think CR is overrated but I do think GF is but thats me.
While I do find CASINO ROYALE a little bit overrated (not much, but a bit), I completely agree with you on GOLDFINGER, which is not only the most overrated film in the franchise, but also amongst the worst (although it will never rival the absolute awfulness of THE MAN WITH THE GOLDEN GUN).
I think Goldfinger is somewhat overrated. I do like the movie, but I don't get why people think it's so great (and I really don't get why people tend to like Pussy Galore so much).
As far as Dracula goes, I've always been fond of the bald, rat-like appearance he had in Nosferatu.
That is by far for me the most disturbing looking version of Dracula though not officially both Kinski's and Schreck's take are the most nightmarish to date they certainly don't make me giggle like whenever I see Lee's much cliched version.
