I can sum up this opening in two words… plain freaking awesome. Though for the most part this OP's visuals are minimalistic, the song and the way the visuals are used just phenomenal.
First off, the song is just great because, well it's a catchy song that sites my tastes, but the visuals match the beat of the song extremely well, which makes it easier to get swept away by the song.
The visuals themselves are rather bare bones but they serve as a reflection of some of the main themes covered.
Towards the end of the video, the opening kicks into high gear and gets even better. Just the shear awesomeness of tail end of this opening is too great to describe in words. Only your eyes can bear to the glory of this OP.
