I thought that the finale was fine.
The Cyber-Time Lord was an interesting concept. The ideas that the Doctor was found, is the source of the regenerating power of all the other Time Lords, and has many forgotten lives are also interesting.
I love Whittaker as the Doctor.
Jodie's doing a great job as The Doctor. I just like all the whiny fanboys who complain all the time that they won't watch the next episode yet tune in the following week to whine more.
