8) The Day of the Doctor
This may be a controversial opinion, but I’m gonna put it out there; I think this episode is slightly overrated. Yes, we get to see David Tennant again (which is always a good thing), John Hurt gave a wonderful performance as The War Doctor, and the Tom Baker cameo at the end was a very welcome surprise, but this episode lacked a certain something given that it was the big 50th Anniversary episode. I feel like there was too much focus placed on the Zygon plot, and not enough focus on The Time War. Obviously the saving of Gallifrey at the end was a brilliant move, but it undermined the whole dynamic of the first two/three seasons; that The Doctor is the last of the Time Lords and has to live with the fact that he destroyed his own people. It is good, but not everything that people make it to be.
