Yeah and the 2-hour movie would also get a bonus for sound.
Comics are visual, but in a freeze-frame sort of way.
There are things that go on between the panels that are understood and require the same bit of imagination that books do. Leave it to Stephen to figure out the numbers. I thought so. Consequently, the demand for a paperback novel is much higher than that for a comic book, which drives the price up. Secondly, the major difference is that the comic is such a visual medium whereas a book really isn't.
