Batman DQ

I was really interested with how they talked about the marketing of this film. The marketing ploys in 1989 were very in-your-face and direct with the same message broadcast everywhere (radio, TV, shirts, ect.), whereas the films now have more of a subtle tone. Did the people actually like and want to see Batman because they thought the actually movie would be good, or was it because of the marketing campaigns in place? Do you think all the added extras have an effect, or do you think the movie would still have done as well if a more subtle approach would have been taken?
