I'm with you. I totally judge a book by its cover. Or if it's written by a friend. Or if it really, really sounds good. Or . . . I think I just talked myself out of this! :)
Lol, when it comes to art I'm the exact opposite. I think I'm not too impressed with the Across the Universe cover because of the people. I've found I don't mind illustrations of characters, but when there are actual models it hinders my view of the characters.
