26th March 2025 marked 20 years of the revived Doctor Who series. To celebrate such a big milestone of my favourite show, I began a rewatch on that day of the entire New Who run, beginning with Christopher Eccleston's Ninth Doctor. Just this afternoon, I finished that marathon at the conclusion of Ncuti Gatwa's tenure as the Fifteenth Doctor.

Along the way, I ranked every episode in order of how much I liked it. You may be thinking that I've done this before, and you'd be right, I did indeed count down my favourite episodes back in 2017! However, I didn't rewatch every episode in the lead up to that, so I can say this time round, every single episode has had a fresh viewing, and it's prompted some significant changes from last time (from memory, I've purposely not referred back to the old one as I don't want my opinions to be swayed!).

I'll be revealing my order from least favourite up to favourite, and I hope you can join in along the way to share your thoughts! What I will say is that spouting unnecessary hatred for any Doctor, companion or showrunner isn't welcome in this thread, as I'll be celebrating episodes and moments from every single era of New Who, and even the weakest episodes have something worth watching for - that's why Doctor Who is such a magical show, no concept or episode is without merit entirely.

I'll start this countdown on Sunday as I'm super busy tomorrow but wanted to get this up in advance! Take your predictions, root for your favourites, and let's relive 20 years of the best show in time and space.

I've also used a spreadsheet made by PigginTeaBreak on Twitter (and modified slightly by me) to rate every episode out of 10 (with 11 for my favourite) and calculate averages for a number of different categories. I won't be revealing each score as I go, as I find them a little arbitrary, but to give you an indicator:

By Series

8.6 Series 1 [Eccleston]

7.5 Series 2 [Tennant]

8.3 Series 3 [Tennant]

9.1 Series 4 [Tennant]

8.0 Series 5 [Smith]

6.9 Series 6 [Smith]

5.5 Series 7 [Smith]

7.3 Series 8 [Capaldi]

6.8 Series 9 [Capaldi]

7.3 Series 10 [Capaldi]

6.3 Series 11 [Whittaker]

6.6 Series 12 [Whittaker]

7.4 Series 13 / Flux [Whittaker]

9.0 60th Anniversary Specials [Tennant]

8.4 Season 1 [Gatwa]

8.6 Season 2 [Gatwa]

Worth noting in the above list who the most consistent Doctors are - Gatwa and Capaldi's series don't vary that much! I'm surprised that both of Gatwa's seasons have a higher average than Smith's first one or Tennant's first two, but the reasoning for that will become clear soon...

I will be here and enjoying every last minute of this ranking but if you rank Rings of Arkatan anything other than bottom 10 we will be having words...
