To me, you really can't compare Chris Cornell to Adele's performance. Not only is it in the right style (epic, operatic, etc), but it sounds both modern and works as a throwback all at the same time. In the modern era of Daniel Craig, whatever you may think of the quality of the last film itself, I think it's fairly unquestionable that the Skyfall theme and opening are #1.
I wonder how many of you guys just like Chris Cornell or Soundgarden in general? Because if you are fans, then that's clearly why you like this song, and it is a pretty good song for what it is, but it surely doesn't stand up to some of the many classics from Bond's history. I feel like I'm taking crazy pills here, because I think this is definitely one of the more forgettable theme songs from this entire franchise.
