Series 8 was a little rough. Very dark, very unsure of itself. But Series 9! I feel Capaldi does a much better job of putting his own little spin on The Doctor! Sonic Sunglasses! Rock Guitar! and he even develops a much more tolerable sense of humor (series 8 his humor was really dark and hard to take). I'm glad The Mistress came back. The Master was always my favorite Doctor Who "Villain" and The Mistress keeps that character going in a very interesting way. Also it proves that Time Lords can switch genders in between regenerations. Who knows, The Doctor might turn into Emma Thompson in the next seriesAnd then I also recently got into Game of Thrones so seeing Maissie Williams become a recurring character in this series was a trip for me! Phenomenal actress and she's only 19! I hope she keeps going with her acting career because I think she can do great things in the future (I mean, what can be greater than Game of Thrones AND Doctor Who?) Sure Seires 9 had a rough episode but episodes like the Zygon Inversion where he pours so much of himself out there for others to see remind me of the David Tennant days. So much raw emotion. This is the series that made me believe that Capaldi IS the Doctor!
