Same - I really enjoy the Master and Doctor parts, and I can absolutely see why the Master was so worked up about the Doctor being more special than him, but the whole thing really didn't hang together for me. I mean, if the Master is just now getting around to building Cyber-Lords how did he wipe out Gallifrey in the first place? And why didn't the dead Time Lords regenerate then, since they can do it now?

And the Doctor not having to push the button was super weak, though I did enjoy the Master being very into it!

There's so much just left unplotted, even if I really like Martin!Doctor and having more than one timestream of Doctors and Masters.
