Perhaps it's because it's a cinematic masterpiece or perhaps it's for a scantly-clad Jessica Alba
All kidding aside it's fine not to like a movie but Sin City to an ignorant person might be distasteful but like I said it is a cinematic masterpiece and was probably one of the best films produced this year right next to Upside of Anger and Cinderella Man. Also I attribute it being number 2 more to Amazon.com running out of copies.
