Sounds pretty cool to me!
Taken from Doctorwhotv.co.uk:
There has been a lot of speculation about the title sequence to Series 8. Certain changes were inevitable with a new Doctor taking over, but is it more than just a name change and Matt Smith face swap?
Guest contributor Paddy O’Meara, who attended the Deep Breath premiere, provides some details.
While I managed to avoid any spoilers relating to the script / episode leaks, I chanced upon a fan-made title sequence by Billy Hanshaw on YouTube (embedded below) which numerous comments stated were being used as the basis for the official title sequence.
As it turns out (and I don’t often say this) the YouTube comments were right: this is very recognisably the same idea, but with a number of changes. The clockwork tunnel stuff at the start, and the lovely shot of the TARDIS flying out from the clock face and spinning back into another, remain in the new version. Other than some polish and font changes, it’s almost the same.
It is after this part of the sequence that things change – rather than the quite simplistic tunnel effect we instead get something a little more akin to the previous titles, flying through space and planetary systems. The Seal of Rassilon symbol is also removed.
The other major change is the face. On the original Capaldi’s face appears on a fob-watch, morphing into a smile before spinning into oblivion. I actually rather liked this, but with the new titles we instead have the now-classic Capaldi “angry brow shot” as seen in The Day of the Doctor, flying out at us as the clockwork gives way to space.
Oh, and they’ve changed the theme again as well: unfortunately the whooping and cheering of the Cardiff crowd made this a little harder to accurately describe, but it’s definitely more of an electronic arrangement this time around.
