Well finally got the chance to come on here and talk about the Next Doctor. Have seen it twice now and I don't think my opinions have changed from one viewing to the next.
A very good episode, let down only by a few RTDisms (but for the most part not his worst RTDisms.)
Morisey was fantastic, for a while I almost wished he was the 11th Doctor. Tennant was superb as usual as well. The stand out of the story was Dervla Kirwan though, fantastic. The bit where she says Mercy was wonderful, and I loved the Cybermen graveyard massacre. The woman playing Rosita was fun but not the greatest actress in the world.
Though the Cybermen were much better here than in s2, they had more personality and felt more like classic Cybermen to me.
On the downside. Sorry but the Robot was a tad too silly for me, and though I thought the CG was ok, it didnt move right as far as I'm concerned. No comments about no mention in history of a giant robot attacking London (apparently Londerners didn't see the loch ness monster either

) but it was a bit RTD going big and epic for the sake of it, which is a shame as the quieter moments here show RTD at his best. Still at least the Cyberking didn't outstay its welcome.
One thing that does annoy me is the contant need to big up the Doctor. Oh isn't he brave, isn't he wonderful etc etc...let's be honest here. Who was braver in this episode? The Doctor (with his regenerations to fall back on, his knowledge and sonic screwdriver) or Jackson Lake? So I could have done without the three cheers for the Doctor stuff at the end...oh and whilst I'm in rant mode. We get it already you know Russell. The Doctor's lonely, companions always leave him, boo hoo yadda yadda yadda- please stop hitting us over the head with that!
Anyway, aside from those small niggles I thought it was an excellent episode. Looking forward to the planet of the dead (and really hoping the 10th Doctor doesn't just trip over a brick)
