Frankly, I lack an understanding of the disdain for "All I Want For Christmas Is You" - I have heard much more annoying Christmas songs. It may be a bit cloying and heavily pop, but I think it's well executed, at least compared to almost any Christmas song put out by a major artist in the 21st century. Also, I think My Chemical Romance pulled off a rather good cover that perhaps beats the original.
Maybe part of it is I have a 5 hour personal/family Christmas playlist that reduces the amount of repeated listens to a more manageable degree. In addition to more well-known ones and several covers, it is also filled to the brim with alternative and indie Christmas music - Jonathan Coulton especially is good at making atypical holiday songs that don't get annoying.
Haven't purchased it yet. I need to read it, but I've had a difficult time tracking down issue 30 in comic book stores - I got behind and have everything else in the other spin off series.
