I have to agree Blink was my highlight ep so far and it was a Doctor LITE ep!
On this ep, parts I loved parts, not so much. First off, Simms was super! I heard someone describe the phone conversations as bitter phone sex

and I agree. Love the Gallifrey parts, I always adore backstory characterizations parts. I like the little balls. More effective than Daleks, while still being a bit Daleky.
LOVED Martha getting pissed at the Doctor! ITA that the Doctor being pissed at Jack being with Torchwood was great. I was kind of sad we didn't have more of the Torchwood cast cross over. Could have been some very interesting clashes there butthe Torchwood staff seeing the Doctor might have made the interactions of the Torchwood staff better than the messed up mess they are.
Dislikes ~Jack does need to so something more than die, a bunch

Hated the make up. HATED that whole turn of the story at the end. What point in making the Doctor OLD? Why send Martha to earth? What can she do to fight down there? Was I missing some plan?
Again HATE the old makeup. BAD BAD BAD! Made worse because the day before another show ended with BAD OLD PEOPLE makeup! Two in 24 hours Pisses me off!!!
Spook~ I wasn't even fond of the Old makeup on Farscape. I did see another show sometime last week that did have good old person makeup and now I can't remember which it was. {damn brain} I just remember seeing it and going OMG, that looks amazing.
Oh and LOVED the lazar screwdriver

Master's screwdriver is bigger than The Doctor's screwdriver

OMG the TARDIS!!!! Being gutted,

I was totally shocked!
Hated Martha's parents. They made the point to stir Martha up but as characters they are so not redeemable. Especially the mother, but honestly, I hate them all. I think after having Rose's awesome family, even Micky, they should have stayed away from that aspect of companion story.
