We just finished watching Series 5, and let me tell you, the second time around it really made a lot more sense. I’m looking forward to Series 6 making more sense, too, since I still don’t have any idea what happened in that one! I definitely like Eleven a lot now, and I like Amy more than I did the first time, but Rory is still by far one of my favorite companions. I think part of it has to do with the fact that he’s a very normal person thrown into extraordinary circumstances, and he shines like star. He doesn’t really get all these fantastical things that are happening to him, and he really doesn’t want to be in the TARDIS, but when he has to be, he’s as strong as Amy or any other companion.
One thing that I did notice this time that I didn’t get on the first viewing of this series was the fact that everything centered around Amy. I knew that the whole scenario presented in “The Pandorica Opens” came from Amy, but I didn’t realize that so much of the whole series revolved around her, too. The entire story was really well done. However, I can’t help but feeling that there’s way too much “destiny” involved with the companions. It started with Donna, with the Doctor realizing that all of the timelines converged on her, explaining why she encountered him a second time after refusing to travel with him in “The Runaway Bride,” why the Ood considered her so important, and why she had such an important role to play in the final encounter with the Daleks. Then there was Wilf, who also was tied to the Doctor by destiny. And then there’s Clara, who was tied to the Doctor because of her actions in fixing her timestream. Thus, the stories of four out of the last five seasons were driven by the companions. (I’m not sure about Series 6, as I remember very little of it.)
While I like the general idea of the universe pushing certain events to happen, I’m getting a bit tired of it happening over and over again. It’s a cool concept only if it’s used sparingly. With probable new storyline of the search of Gallifrey and the fact that Clara’s “Impossible Girl” story has concluded, I can hope that the series storyline will not be so companion- and destiny-centric.
