It's bad...really really bad. Almost as bad as the theme for Colin Baker during the Trial of a Time Lord episodes. Don't get me wrong, I'm not opposed to something different, I love the star field/electric guitar themes that lasted from late Tom Baker to early Colin Baker. Hell, I absolutely adore the Sylvester McCoy opening visuals and theme. All of those were very different from what came before. Maybe it will grow on me, but my first impression is that this new clockwork motif and theme make last years photoshop copy and paste blobs look good in comparison. Maybe I would like it better if the music was better. I haven't been the biggest fan of the music after the Eccleston era, but it hasn't been as blatantly offensive as this new atrocious theme. Now of course I'm not really that worried about it, It's not going to have any effect on what I think about the show or the episode itself, it's just a minor nitpick.
