Anyway, it looks like the Theme for the season is going to be along the lines of “The Doctor *needs* Companions to keep him from going off the rails into megalomania. After all, the Time Lords aren’t around anymore to keep him in line.
(snip)
Anyway, we are clearly shown that The Doctor needs Companions to keep him morally grounded – in keeping with the apparent theme for the season.
Actually, I'm pretty sure this was the theme of the Tenth Doctor's season with Donna (and through the end of his tenure). Her shouting, slapping, etc. and "Earth-girl"-ness was generally in response to his giddy/pompous "spaceman"-ness. It was not only fun to watch (for me), but I think it made Donna the absolutely perfect companion to the Tenth Doctor. He had perhaps allowed his own self-importance get inflated after two starry-eyed/swoony companions with romantic feelings, and Donna's absolute refusal to take his proclamations as ultimate authority (as well as her inability to see him as attractive) was exactly what was needed to "ground" the Doctor's ego and pull him away from that "Lonely God" archetype. And once Donna was gone, he regressed heavily into that persona; after a light moment in The Next Doctor where he managed to briefly connect with the deluded Jackson Lake, he went around on his own, turned down the Bionic Woman as a companion for fear of losing someone else, and then in Waters of Mars he practically broke time itself not only to keep alive another woman he came to respect, but also because he realized that there was nothing stopping him from making the attempt. I thought The End of Time did a good job of wrapping up that story, as the Master and the return of the Time Lords both showed the ramifications of what the Tenth Doctor might become if he kept going on; defeating them both not only showed his rejection of that path, but put him on what I thought would be the next sensible step: "stepping down" from that "God" pedestal that he'd climbed up on, and engaging/reconnecting with the Universe and the people in it on a more personal level. I thought that was well represented by the fact that, immediately after saving all reality from all the other Time Lords, his next (and final) act was to sacrifice himself (well, the Tenth Doctor version of himself) for just a single good man, someone whom he'd felt a strong personal connection to.
Unfortunately, Moffat seemed to ignore all that wrenching character progression as Eleven banked on his demi-god-like reputation multiple times in his first two seasons before finally considering the notion of stepping away from his self-appointed role of grand savior. Not that the Doctor hasn't earned the right to play up his importance, but there wasn't any indication that he'd learned or accepted or even changed from that aspect of the Tenth Doctor, which undermines the notion of each regeneration having its own distinct persona. But it also seems like Eleven's borrowed a significant amount of other traits from his previous lives in addition, and that's kind of disappointing because it means that Moffat's just coasting on previously-established characters rather than making something new and interesting. Which is too bad, because Matt Smith has done a fine job performing all the little personality elements that make up his pastiche of a Doctor, and I'd really like to see what he could do with a real direction and character arc for Eleven.
Even more so, I feel like Moffat has missed another great opportunity of his own design: he brought onboard Amy and Rory as a couple, with Amy as a woman whose life was messed-up (however inadvertantly) by the Doctor's lifestyle (the TARDIS made the Crack and skipped the Doctor over her youth), but who found a stable, happy, loving relationship with someone anyway. Having them and their "domestic" lifestyle paired with the Doctor would not only give the show a new dynamic (a "couple" on the TARDIS), but could showcase Eleven engaging with those "human"/non-god-like perspectives that he'd so desperately lacked as Ten (and to some extent, as Nine). Instead, we got the Crack erasing the Universe and scrambling timelines and the companions' memories, followed by the mind-screwing Silence and an even more scrambled timeline as Amy and Rory become parents, have their ch!ld **70**, get left on Earth repeatedly by the Doctor, and only reunite after time actually does get broken (but despite the lessons of Waters of Mars, the only remarkable aspect of that event is that the Doctor apparently gets married). So rather than show the Doctor's new personality and develop a character arc for him, or even establish Amy and Rory coherently, there was a massive mishmash of crazy time-traveling/reality-breaking events that sounded (and even looked) good as ideas, but made a mad mess of the show's continuity and seemed to barely affect the Doctor's entourage.
Ultimately, I probably won't be rewatching most of seasons 5 and 6 (apart from a handful of gems that I really liked a lot), and so far the same goes for season 7. That said, I *am* looking forward to having a new companion on board, because it means new opportunities for stories and development with the Doctor and the new character, and I'm hopeful that they won't be wasted this time around.
