A comic will always be more 'personal' than a DVD or CD, both of which require electronic 'players' to decode their content. With comics, the reader is the player so the engagement with the material is always more fundamental and dynamic. Reading comics is a much less passive activity than consuming CDs and DVDs.
Seven actors have played Batman on the big screen, and if you can name all seven without reading any further, your youth has been wasted.
I do like to keep abreast of what the hardcore vocal members of the comics-reading audience are talking about on Internet message boards, but there are so few of them, as a percentage of the buying audience, that I can't allow their opinions to dictate story direction.
