I watched the first episode after returning from Edinburgh and was extremely tired but it didn't seem too bad. Martha at least has some useful skills - being a nearly-qualified doctor means she should be quite an asset to the Doctor, who tends not to be big on repairing the damage he inadvertantly creates. The whole hospital thing was alright - though Martha was perhaps a little too cool with it while everyone else went to pieces. Perhaps she suffers slightly from being a little blazé about danger (this is RTD's way of putting a "Companion Badge" on her perhaps?), but not to the ridiculous extent of Rose in series 2. However she's only been around for about 2 episodes, so I worry about her later wise-cracking. I will rewatch it on my Sky box next week while I'm recording it onto disc.
Also one thing I am most assuredly not waiting for is the Jones family soap opera. Daddy Jones is shacked up with a dolly-bird blondie, who I am sure will inevitably prove to be the most annoying character in the show next to Rose. I imagine she will get quite tiresome and will inevitably end up captured/possessed/whatever.
The second episode, the Shakespeare Code, was very, very good. A lot of work went into getting the period just right, though this seemed a bit wasted since our main characters as usual made no effort to blend in and dress/act appropriately and I felt they give old Tremblestaff too much of the old common touch. At least the humour wasn't as jarringly forced as Tooth and Claw, last year's historical episode. Then again this wasn't an RTD episode.
I liked the villians. Nearly as cool as the Ood. I hope the Carrionates come back at some point - the main witch villainess was disturbingly hot. I worry about me sometimes. Well someone has to. Sadly they probably won't come back - they're not an RTD creation. To wit, next week - we return to New Earth. Because like all RTD's "innovations" it was so good it simply had to be revisited (cue rants about the year 5 billion looking a little too much like 2007). On the other hand if this kickstarts the whole Last of the Timelords plotline it might be worth watching.
Rose seems to be getting namechecked a little too much for me. She wasn't that great. Get over it, Doc.
Otherwise, much better season so far.
