My all-time favourite series is Series 4. The reasons why are: 1) There isn't a bad episode - although the episodes can range from being amazing to pretty average in quality, they are all great fun to watch and I would happily re-watch every episode at any time. 2) AMAZING doctor and a very good companion - David Tennant is perfect as the Doctor while Catherine Tate brings something new to the role of the companion. The pair have superb chemistry and I pag-ibig the "journey" Donna goes on as a person. 3) We also have the return of Donna, Rose, Martha, Jack, Sarah-Jane, Mickey and Jackie. It feels like 4 amazing series (as well as spin-off shows Torchwood and SJA) has led up to the tense finale. 4) The villains and settings are also wonderful.
I personally believe this was the peak of Doctor Who's 50 taon history and honestly it's no surprise!!!
I pag-ibig all the series but my paborito is series 4 cause' I pag-ibig the chemistry and the comedic timing between David Tennant & Catherine Tate. The episodes are fun and exciting and I pag-ibig it when all the companions come back. Seeing that was so cool. I really enjoy that season. :))
