I take comfort knowing there is at least one argument here that I'm not involved with. 
Oh yeah? You wanna fight about it?

Blink = amazing, though it seemed too short: me and the girl have theorized that had it been a two-parter, more time could have been spent building up the creepiness that is the weeping angels.
DISCLAIMER: THIS IS JUST AN OPINION, AND SHOULD IN NO WAY BE REGARDED AS IRON-CLAD FACT.(Except it totally should, because I'm always goddamn right and well you know it.)I probably mentioned this in the LJ posts I linked to, but I found the Weeping Angels a bit weak, because all they did when they finally caught up with you was send you back in time, and most of their victims seemed to be happier for it. It was mighty clever (like so many other things on
Who) but I kinda felt they were wasted.
Also, I still wish Sally Sparrow had gone on to become a full-time companion. Or just transported herself to the real world so she could date me.
The "data ghost" effect in "Silence in the Library/Forest of the Dead" was probably the most jarring element of the whole story. I thought the monster itself was weak.
The scene with Donna comforting Miss Evangelista's data ghost as she faded out was one of the most effective "tear-jerker" moments I've ever seen on screen. Like I've said before, those
Who writers know how to play a riff on the old heartstrings.
"Midnight" was amazing. The way the other crew members lost their rationality did a lot to add to the episode.
Pretty much a tutorial on how to write a gripping story set entirely in one room. The tension started building fom the moment the co-pilot saw the shadow outside running towards the ship, and didn't let up until the very end. When people tell me the Weeping Angels were terrifying, I can only point them towards the Whatever-It-Was in
Midnight. Not only because you didn't know what it was, but because
you never found out what it wanted - its motives were never explained, and may well have been incomprehensible to us if they had been. Now
that's a frightening alien menace.
And based solely on her performance in this episode, Lesley Sharp is now officially the Scariest Woman Ever.
Martha's ass distracted me most of the 3rd season. 
No arguments there. Amy's miniskirts had much the same effect on me throughout Season Five.
