No it is not. Torchwood series two occurs before the end of Doctor Who series 4. The Doctor Who series 4 finale has big spoilers if you'd not seen all of Torchwood series two.It's set after this season.I haven't seen Torchwood season 2 yet, is it set after Dr Who season 4?
I take it that most of the time we hear the Daleks talking English because they are around characters that the TARDIS is automaticaly translating for (loved the demonstration of that in the Pompeii episode!). Martha no longer has the TARDIS doing that for her so she heard the Daleks using German to speak to the locals.Yes! Still doesn't explain why the Daleks speak English at most other times when they're not in Britain though... e.g. on Skaro (-_-) I wonder what Dalekese sounds like.
Damn straight.David Tennant is widely considered to be one of the best-looking Doctors (rivalling Peter Davison (5th Doctor).
12 regenerations? I'd say they could get around that with a bit of "it seems the limits the Time-Lords had on regeneration have ceased to be, since the Time War changed everything.."
Martha's fate is tragic. Boo! Martha was the best companion so far. I will miss her.
