All 13 modern Doctor Who seasons ranked from worst to best
5. Series 10
Series 10 was Steven Moffat's last season as showrunner, and that fact contributed to both the best and worst of this season. Overall, the season is relatively forgettable. Bill is a great companion, but most of the episodes just don't have the energy of Doctor Who at its best.
There aren't any really bad episodes, but few stand out other than the season opener and the final two episodes. Capaldi's version of the Doctor seems tired after losing his wife in the 2015 Christmas special "The Husbands of River Song," and it seemed like Moffat had already finished telling the stories he wanted to in earlier seasons.
Despite that, the finale of Season 10 just might be the best Doctor Who has ever had. Where earlier episodes felt recycled in a tired way, "World Enough and Time" and "The Doctor Falls" felt like the culmination of Steven Moffat's Doctor Who career. It featured the first-ever Multi-Master story and captured the Doctor at his absolute best.
Michelle Gomez did an amazing job with both the chaos of the Master and the growing empathy she developed over the course of the season. Peter Capaldi performed a speech that defined the Doctor perfectly. In many ways, both the Doctor and the Master's arcs felt complete, so this could have been a strong series finale.
