The Shakespeare Code was a romp, not to be taken seriously but great fun. If I were to pick at it I would suggest that we try a purely historical episode, perhaps, without (other) aliens? I would also suggest that I wasn't quite as much in awe of the aliens as the production crew seemed to be in that week's Confidential, CGI-wise they seemed to be to be much of a repeat of those from School Reunion. But I did like the quasi-cliffhanger with Queen Elizabeth. Clever, and I wonder if it is a prequel for something. Didn't Babylon 5 once do something similar? Virgin Queen in Not Played By Helen Mirren, Judi Dench, or Glenda Jackson - Shocker. Now, to quote poliphilo, that's what I pay my licence fee for.
Gridlock: Didn't look promising, but turned out to be nicely done. I suppose RTD can do the satirical element - see also Bad Wolf. It was a bit derivative - not just the Macra (which were almost an aside), but also The Ark/Ark in Space, The Face of Evil, and weren't those sisters a bit Paradise Towers?
Daleks in Manhattan/Evolution of the Daleks: Couldn't we have called this The Manhattan Project? Musical theatre - ha ha ha! Yes, perhaps it was derivative again (Evil of the Daleks is not a story I'm familiar with, but in many ways, think Destiny too). If there were a Cult of Skaro, wouldn't it be populated by renegade Daleks, tempted to go about the universe doing good? And surely a Dalek-Human hybrid would restore some of the emotions bred out by Davros. Like Genesis, the Doctor has the option to stop the whole thing, but ... he can't. A nice touch with the Doctor seizing the antenna so as not to be electrocuted - a Faraday cage turned inside out; nice line about the sonic screwdriver. First Floor - Perfumery! There were flaws, but I think the high-level story had something going for it.
Generally I think this has been a rather good season so far.
