David Tenant was the best Doctor

Relationship With Companions The big thing to take into consideration about D11 is that he was the first Doctor of the newest incarnation of Doctor Who to stay with his full time companions (ie: companions that feature in all 13 episodes of a series) for more than one series. Sure, Rose Tyler may have been around for two series, but it was with different Doctors, and she, along with Martha Jones and Donna Noble, only ever made bit part appearances after their initial 13 episode runs with D10. But I digress - the above essentially means that D11 was the first post 2005 Doctor to establish real depth with his companions. Case in point, Amy Pond, who he meets as a little girl immediately after his regeneration in the Eleventh Hour, and then meets again some 20 years later when she's a fully grown adult, while we learn from other episodes that she ended growing up idolising the Doctor. After another wait, Amy is eventually taken in by the Doctor, and despite some setbacks to their relationship (Amy choosing to "forget" in the Beast Below), they grow closer due to things like Amy ceasing the torture of the Star Whale as well as saving her from being killed by a Weeping Angel in Flesh and Stone, they grow closer, although D11 needs to stage an intervention when it becomes clear that she is developing "extra" feelings for him, leading to Rory Williams getting invited onto the TARDIS. The introduction of Rory as a master stroke, as he plays the role of the Only Sane Man attempting to keep Amy grounded in reality, and serves as a more realistic companion than someone like Rose as he does not immediately trust the Doctor and genuinely cares for his romantic partner. After briefly dying, Rory and D11 gain mutual trust and admiration for each other after what they do to save Amy in both The Big Bang and later on in A Good Man Goes To War, and the relationship between D11 and his companions is improved when it's revealed he trusted them with a mission relating to his death (the blue envelopes in The Impossible Astronaut) as well as the fact that Amy is able to persuade D11 to take on the mission despite it coming from an anonymous source. River Song also plays a role in helping the companions and D11 grow closer, as she helps with the rescue of Amy in Flesh and Stone, inadvertently helps bring Rory back in touch with Amy and D11, and of course the fact that she is revealed to be none other than Melody Pond, the daughter of the Ponds, and the woman who loves D11 so much she gives him her remaining regeneration energy to save his life, as well as initially refusing to kill him in The Wedding of River Song before being shown what D11 actually is (the Tessalecta), and she also plays a big role in the Angels Take Manhattan where she helps deliver the book written by Amy with a farewell message to D11. Amy leaves D11 on good terms and of her own free will to be with Rory, and leaves D11 with a heartfelt goodbye. This then leads to the mystery of the new companion, Clara, and who exactly she is. After being saved by versions of her in Asylum of the Daleks and The Snowmen, D11 becomes obsessed with finding out who she is, and growing ever closer to her especially after Clara defeats the Sun in Rings of Akhaten and her remembering their interactions from Journey To The Centre Of the Tardis in The Name Of The Doctor, it builds to the brilliant climax and sealing of the strength of their relationship when she enters D11's time stream. Now to rebut Pro's R2: Quality of D11's achievements Pro asserts a number of achievements on D10's part. To object to those achievements I have issues with: I will point out that his defeat of the Sycorax was cancelled out by causing Harriet Jones to be removed from power, which in turn lead to the events leading to the Master becoming Prime Minister. Similarly, what he achieves at Canary Wharf couldn't have been done if Rose hadn't fixed her lever, while we learn in Turn Left that he would have ended up dying from trying to stop the Racnoss without Donna there. Furthermore, Dalek Caan still escapes from Manhattan to save Davros, and D10 doesn't take any measures to ensure that nothing of the Master remains, leading to the events of The End Of Time. As for Journey's End, D10 essentially amounts to a male damsel in distress in this episode, saved only by Donna's time lord awakening. And while I have no objection to his defeat of the Time Lords, I DO have problems with him railing against Wilfred Mott as well as his abuse of a future regeneration, in stark contrast to the reassuring way D9 talked to Rose about the forthcoming D10. And I don't think that saying "I don't want to go" counts as "embracing his death". Quality of Individual Seasons and Finales While I will agree on the quality of Series 2, I will point out that while the first half of the series is pretty awesome viewing, the second half aside from the two parters produces one largely forgettable episode (Idiot's Lantern) and two straight up awful episodes in quick succession that are considered among the worst in New Who history (Love and Monsters, and Fear Her). Furthermore, while the finale certainly delivers in emotional content and the awesomeness of Daleks vs Cyberman, it gets way too melodramatic at the end with both the false nature of how "Rose" dies (compare to the more emotional way of how Amy and Rory ACTUALLY "die" in their final episode) as well as Rose being a drama queen even though she has loving family members around her that are all alive, which is more than what she had at the beginning of her time with the Doctor. Series 3 is pretty good but is excessively dominated by D10 grieving about Rose even though she isn't actually dead (and in hindsight it makes Series 3 worse when we find out Rose was able to get back into our universe after all) and the series doesn't really allow the D10/Martha relationship to truly shine until The Lazarus Experiment, and even then the very best episodes of S3 are the ones where D10 is very much a background character (Blink and Last of the Time Lords). Moving on to S4, it was a significant improvement as Tennant became considerably better when he wasn't doing his illogical mourning, but again S4 was dominated too much by the fact that "Wow! Rose is returning!", which is irritating because due to reasons I will expand on in my R4, I believe Rose unjustifiably dominated the Russell T Davies era of New Who as her negative character traits strongly overshadowed the good. I have little other issues with S4 except for the treatment of Donna in the finale and the awful use of the Reset Button in turning her back into the not very intelligent person she was back in Runaway Bride. As for End of Time, D10 is just as guilty of trying to avoid his death as D11 is with his wiping away from existence, as D10 is said to have spent a while avoiding going to talk to the Ood, and there's also the part I mentioned where D10 talks about his lack of emotional connection to his next regeneration and how he hates how "someone else" will walk away with his memories and he'll be dead, which is utterly out of character for any time lord and hardly a glowing message of support for Tennant's and Davie's successors to the Doctor Who team. There was also again D10 completely unjustifiably railing against Wilfred Mott for "causing" D10's death deciding to save Wilfred's life, which just smacked of D10 showing arrogance, self-pity, being flat out mean, and making claims to having a high ground morally when not really having one. And as I said before, "I don't want to go" was just stupid considering Tennant and Davies were leaving willingly and weren't exactly being dragged away, and it would make the job of the next DW actor and team incredibly difficult when the last words of the previous incredibly popular DW actor was as above. I'll tackle the "companions" part in R4. Over to you, Pro.
