I see Blade as the first glimmer that comic book superheroes beyond Bats and Supes could become successful movies. Most of the pre-blade titles mentioned (Dick Tracy, The Crow, Timecop, The Mask, and Men in Black) aren't what I would think of as the traditional long-underwear crowd.
I don't think the general public sees Blade as any more of a superhero than the Crow or Timecop, or are any more aware that the character originates in comic books.
Dick Tracy and
The Mask wore their comic book origins on their sleeves to a much greater extent, even though Dick Tracy of course isn't a superhero, while the Mask has super powers but uses them for selfish ends.
X-Men was really the first non-Superman/Batman comic book superhero film - that was recognizably superhero and famous as a comic book - to score at the box office.
