“Vincent and The Doctor,” when the Doctor takes Vincent to the Musée d'Orsay. I love how the background music starts as diegetic, playing from a boombox, then you have a wide-eyed Van Gogh taking in all of the exhibits. I’d love to be able to tour a museum like that with a master of the craft. It culminates with Bill Nighy’s curator character giving a glowing description of Van Gogh’s body of work with the man himself standing right behind him, and it’s time to turn on the waterworks.

"A Christmas Carol" springs to mind as one of my favorites with in-episode time travel. What's more Doctor than trying to save the day by retroactively making the villain your friend?

Dr Who doesn't have that many eps that jump between time in the ep itself so it is a little hard.

I like the Christopher Eccleston run because you see The Doctor have to witness the effects of his actions with the space station.

When rose meets Queen Victoria and tries to get her to say whether she is amused or not.
