@ garth33, another long term whovian ... :thumbs up:
for me i have been watching the show all my life .. something truly unique and special
@ syko2d4. i preface this by saying there is no wrong in a personal reaction to a tv show, movie, music, book, painting, sculpture etc ... your interpretation is as valid as any, but so are those of others
for me and all the whovians i know (and they are plentiful), we were happy to hear smith was leaving. for me i would even say relieved.
and when it was finally announced that capaldi was the next doctor, we were all unconditionally positive about the news.
capaldi can act rings around smith .. and i have been more than impressed with every role that i can recall him in. i have seen him in the shows you mention and at least half a dozen more, and his presence in a cast is likely to make me interested in checking it out
now to a perspective from a long term fan's point of view. doctor who; while being a family show, and popular with children, has alway had an element of darkness .. it is vital to the nature of the show. if we are looking for lightness, bubble and froth there are plenty of shows that offer that, the doctor doesn't need to be light to appeal to children or general audiences (search the term "behind the couch" on wikipedia as a refernce)
hartnell, troughton, pertwee, (t)baker, davison, (c)baker, mccoy, mcgann, ecclestone and tennant all had darkness lurking ... even cushing in the non-canon 60's movies had this characteristic.
(while you may only be familiar with mcgann from the telemovie, remember that the character developed in the radio plays and books)
the darkness is essential to the character of the doctor .. he is the last of his kind, and responsible for that being so. he has taken the role of guardian of the universe on of his own volition, and despite his (varying degrees of a) non violent nature, someone has to lose in all of his actions and confrontations. even before he was the last timelord he was at odds with the others, to the point even of having been exiled to earth without a functioning tardis during most of the pertwee tenure
he has known and lost many friends and companions, some of whom have died on his watch. i remember being deeply moved as a younger viewer at the death of adric for example, something the doctor was at least partially directly responsible for.
to have such a character without darkness, regret, or even guilt, is unconvincing.
as for an american playing the doctor .. you are right .. i would be extremely resistant; but not for the reason you may imagine.
in the uk, and places like here in australia. nz, canada etc .. the show is a genuine institution. actors have grown up with the show, and that knowledge of the history and character is essential to the show.
a recent run of docos preceding the 50th anniversary show proved this .. even the actors who had played bit parts years ago, let alone those from the recent years, can talk in depth about the canon, and all love and respect the show.
further, they embrace the fact that they are forever primarily and indelibly linked with the show, and are proud to be so. the usa is so far behind in this essential characteristic of the show that it is highly unlikely that any american actor could take it on convincingly and satisfy the international audience.
@ all .. how's this for a fantasy .. imagine the great neil gaiman as the showrunner ..
responsible for the script of the best smith episode (the doctor's wife) .. let alone sandman, brilliant dark fantasy novels and several cool movies as well. he loves the show, and has the mind and talent to do it well ....
