Regarding the longevity question, while I don't expect to see it last 26 years (other than The Simpsons and Law & Order I do not expect us to ever see shows of that like again), I don't see any reason why this can't make it at least to Season 10. Proportionately speaking DW is just as popular in the UK as NCIS (now in Season 7 and still going strong) and CSI (approaching Season 10 and having survived its equivalent of a Tennant-to-Smith changeover with the replacement of Gil Grissom). If the demand continues, and if the BBC still makes a profit from DW, it'll continue. There might be some doubt as to whether the BBC will continue much longer, but I would think it a safe bet that if the BBC folded, and again assuming DW remained a money-making going concern, that it would be picked up instantly by either a cable network or even one of the non-BBC UK networks. The only concern I have looking ahead is that I don't want to see DW rebooted, or the clock reset, or reimagined. Yes, reimagining has worked really well with shows like BSG. Yes, rebooting/resetting the clock has brought Star Trek back to life. But the RTD era proved that maintaining the original continuity with Doctor Who was viable and could be pulled off without causing the "canon overload" that alienated so many prospective new Trek fans (forcing Abrams to reboot continuity with his movie). He set the successful precedent, so when the current incarnation of the series inevitably ends, whether next year or 5 years from now, when the time comes for it to be brought back yet again, whoever is charged with doing the job will have more than enough incentive to keep the original thread going, rather than starting over or "fixing what isn't broken". Of course, no one expects the Doctor to die after life 13. The Five Doctors, Utopia, and even in a perverse way the 1996 TV movie showed us how the Doctor could get around it. Some have suggested the death of the Time Lords removed the restriction. If you count the Morbius Doctors or the Cartmel Masterplan as canon, then possibly the limit never applied to him in the first place because of him being The Other or half-human or whatever. David Tennant himself said it is the easiest issue to rectify in the world, and can be done with a single line of dialogue. I would hope whoever ends up writing for the 13th Doctor does take the opportunity to ramp up the tension, but like no one believed Bruce Wayne was really killed off earlier this year, so too I can't see anyone really expecting the Doctor to snuff it after life 13 ends. Especially not if the show continues to attract millions of viewers and make millions of pounds for the BBC and/or whoever owns the property when the time comes. Alex
PS. I have no idea what happened to the formatting of my message. Looks like TrekBBS suddenly forgot how to parse paragraphs. I honestly didn't write one unbroken paragraph like that, but for some reason it won't let me fix the formatting.
