http://www.tor.com/blogs/2011/01/fezzes-arent-cool That, and another article on the same site--very interesting, very positive review of/reactions to Matt Smith's Eleven. Pretty much, my same thoughts--particularly the idea that Eleven's comedy is an overlay for much more going on beneath. That, in fact, is what I really admire about Smith's performance: it's what makes Eleven seem ancient and young at the same time, as well as completely alien under the facade of familiarity. Even more is the sense that there is far more emotion, of a far more complicated, darker nature, than the sweet, eccentric persona. Not to say that I think the sweetness is false or contrived--that IS the Doctor. However, Smith conveys the idea that the Doctor does hide his pain, grief, and anger, keeping them private from others...except on rare occasions when they erupt, as when he shouts at River in "Flesh and Stone." Or he just barely contains them, as in "The Beast Below," when Amy asks him if he is a parent and if there are any other Time Lords.
One exception, where my reaction doesn't match up to the Eleven reviews: I cannot figure out why anyone would think Eleven is "sexless." I'll agree that he avoids romantic entanglements, just as he tries to deflect anyone from realizing his darker side; however, he's as successful at avoiding as he is at appearing only funny and weird....in other words--not at all. Eleven's much more sexual than either Nine or Ten--who were about as repressed as characters could be....Ten, at least, had some encounters; nevertheless, there was a strong puritanical streak to Rusty's version of the Doctor. Eleven can be oblivious, but he also can be interested (as when he eyes the lovely Venetian passing by the TARDIS in "Vampires"). Even more: he doesn't have Ten's prissy attitude; Nine, in Moffat's "The Empty Child"/"The Doctor Dances," was more like Eleven--then he started to drift toward the prissiness.....
Eleven? Sexless? Er--not hardly. So to speak.
