OK I liked and didn't like this ep
First, they've gotten quite wild with the intro stuff. I keep thinking....this can't be Doctor Who, am I on the right channel? Honestly, I've checked the guide at the beginning every week since the Ninja opening.
I don't really like Mickey on board but I loved the lines {Rose} " You can't keep the horse" {Doctor} " I let you keep Mickey"

that almost makes him worth it. I think Captain Jack added something as a third, I even think Rose's Mom would add something, but I just don't like Micky
I thought Ten and Sophia Myles had

WOW chemistry. It was a little disconcerting as both Ten and CE have clearly focused on Rose as a little more than companion vibe. To have the Doctor clearly attracted to another chick in so short a time was again.. disconcerting. I was surprised there was not more jealously from Rose, she was mostly hurt a bit it seemed.
On the other hand the Doctor is not human so attributing human mating rituals don't really apply, so I'm starting to buy that he can "love" many people deeply a one time.
So I'm hearing that Ten and SM were dating when this ep was filmed. Goodness, it showed, quite a shocking kiss for DW.
So it clearly really looked like Ten jumping the horse threw the window {points for that and his form, that part of coming off a fence is very difficult to look graceful in, the jump up is easy, down not so much unless it's a pretty high fence which this looked like it was} altho the overlay from clearly greenscreen wasn't very good.
I hated they cut the scene where Rose tells Mickey {or it comes out} the TARDIS had a homing device to get she and Mickey home if the Doctor couldn't get back. It looked like he'd abandoned them in space. I think I remember the homing thing coming up in "parting of the ways" but still that isn't what came to mind when Micky was questioning Rose. And it made the "how long did you wait" doctor comment not make sence. What a silly line to cut?

OK things I liked, now this is funny cause it's exactly some of the things I didn't like.
I liked they are starting to show the Doctor has different emotions than a human. Having an intense reaction to Madame de Pompadour and still clearly loving Rose, an echo of the Sara Jane ep, I think this is good. Giving the Doctor layers I hadn't seen before. Again, I'm not so much a shipper person with DW but I can see how this will cause a stir among newer more romantic veiwers.
I like that they are mixing up the look of the show. {even if it fools me} For the most part I think the blending of special effects of the newer more modern and paying homage to the older effects is working well.
I like Billie/Rose's acting with this Doctor very much. They have a common giddiness mixed with steel.
Still don't like Mickey
