I just watched "The Impossible Planet" and "The Satan Pit" for the second time. Caught a couple more bits. The only issue I have with it -- if I have an issue -- is that the Doctor goes a little overboard with the "humans are fantastic" thing. Otherwise, the writing is brilliant. The pace never flags, and it's a beautiful example of modern shrinking horror in the first half, suspense/action in the second.
I don't do real spoilers -- it takes away all the fun of seeing people as they watch it unfold -- but I want to make comments. I know I'm more sensitive about spoilers than most, so I'll cut it as I would like it to be cut, and those with more lenient sensibilities can just ( read on. )
It's interesting that after 900 years, the Doctor is still put in situations where he has to search his soul, and find out what he believes in. He's still looking for answers to the questions people unwittingly ask him, not knowing that his answers are rather deeper than most humans'. He's always been a coward, though, as his predecessor admitted -- afraid of what he is deep down, and what he is capable of doing, perhaps more than he fears any external thing.
David Tennant is a very passionate Doctor, in a different sense than Eccleston was -- the 9th was bottled up, frustration and grief and anger. The 10th has come to some sort of terms with who he is now, and is more free to feel joy, enthusiasm, and passion, as well as fury and grief. He's a good balance between the genius and the poet, and I like him a great deal.
So, that's our episode of Analysis of a Fictional Character for today. In a way, I grew up with the Doctor, and I feel like I know him as well as anyone does; he's as real to me as the characters in my head, and I've known him about as long. It makes for a deep sort of attachment... and it's good to see him out there and doing well.
