Well... I hope you don't mind me being the dissenting voice here, but I found this last hurrah of the Tenth Doctor to be
flawed at best. Don't get me wrong, I think it's a fitting sendoff to David Tennant and the wonderful 4 years he's given us. At the same time though, it's an irritating (but thankfully last!) reminder of how half baked Russel T. Davies' writing is at times.
Let me start off by pointing out the big problems I had with this finale:
1) The Doctor's needless angst about death - Sure, when faced with the prospect of meeting our inevitable end, I'm sure we'd act a bit maudlin and somewhat melancholy. So too would the Doctor, if he really was in danger of dying! But the agonizing choice of sacrificing himself for Wilf? Not a problem! Just a radiation bath, one regeneration later - poof! - brand new Time Lord! So why does he need to go on some wangsty rant on how he has so much left to live for?! WTF?! Dude, you can change into a new form! What the hell are you going on about? You've done it nine times already! What's so bad about one more?
Apparently Russel T. Davies didn't get the memo stating that regeneration isn't a death, it's a rebirth. All that foreshadowing he built up since last season of the Doctor's coming end felt wasted. If he really was in danger of dying, make it feel like it is! Don't present a situation where the audience (and the Doctor) know that he'll be reborn. All those farewell scenes to his comapanions at the end (which were wonderfully done btw) felt wasted.
2) The Doctor using a gun - The biggest glaring plot point. So the Doctor needs to use a gun to kill the Master, since the Master is the link to the Time Lords eventual return. The Doctor of course, can't do it, since he's vowed never to use a gun (which is of course bull, as he's used guns many times before), and it's against his code of no killing (despite the humungous body count that can be laid at his feet). He can't kill the Time Lord president either, which would be just as effective in solving the problem.
Then along comes the third choice, shoot the machinery! Right! Brilliant! Why didn't you do it before you stupid git! Of course, it's Davies again and his lackluster plotting. So he pull his out of his ass a cheap solution to resolve the plot. Despite the fact it renders moot all the dramatic tension that occured moments before.
Whew... anyway, that's my rant. Not to say though that there weren't any good points to this show. All the performances were wonderful, especially Tennant, who gives a bravura acting job in his final appearance. While I will miss him, it was a kick to see Matt Smith in the final few seconds. Geronimo indeed.
Bring on the Moff and the 2010 season!
