I wonder ... if we saw the movie version first, and then came around to read the novel, we may have a different opinion/perspective? I know I felt this way with Bridget Jone's Diary. I saw the movie, fell in love (er, with Mark Darcy character), so I was somewhat unhappily surprised when I came across the cover art for the book. Two large eyeballs and mouth cut out to rest atop a blank open diary wasn't exactly enticing me to buy the book ... it was rather creepy, frankly. I did buy it anyways since I wanted to compare the differences from the movie version to the original intent of the book. The "tween" in me wanted to see Mark Darcy (Colin Firth) on the cover too, just saying. :)
