None of those films even comes close to pioneering the "sexy vampire" in cinema. Modernising it maybe, to a certain extent, but definitely not pioneers.
The real pioneer work was done in the 60's and 70's by European directors, who were making highly stylised films which often featured full frontal nudity and sex scenes. Even Hammer here in the UK sexualised their gothic vampire films as much as the censors would allow them to for the late 50's and 60's, even if they did go a bit camp and ridiculous with some of it in the later years.
In US cinema, as opposed to world cinema, it was the movies I mentioned. I think the US movie that followed in the European vein was The Hunger (complete with Catherine Deneuve to give it authenticity.) Which I don't think was very influential in the US.
The Fright Night remake kept most of the story elements developing the sexual appeal of the vampire with a vampire who was a raving monster. This was stunningly inept.
