“Uhh, it’s “Watchmen”, anyone with even passing familiarity with the source material will know it’s not (and not meant to be, and shouldn’t be) kiddie fare.”
Uhh, that’s her point. Most people won’t know what kind of movie it is until they are watching it, some with their kids.
The publicity machine for the, hello, “R” rated “Watchmen” is all cranked up. Book stores are displaying the original graphic novel and various tie in materials that tells anyone even just picking up and flipping through a few pages the nature of the material. Blogs talking about it often make a point about it's adult nature. Even the movie trailers themselves are dead give aways that this is not exactly Superman and apple pie ... (see the trailers if you haven't, it's got death, blood, killing, riots, pretty dark and brooding and a bit nihilistic for a movie trailer edited for all audience)
