Wasn't He raised from the dead?

From the Radio Times:

Martha comes back down to Earth with a bump - and this time it's got nothing to do with the TARDIS's dodgy propulsion systems. She's paying a visit to the quarrelsome family she left behind in favour of a taste of adventure with the Doctor. But she soon learns her nearest and dearest are embroiled in Professor Lazarus's dastardly plans to manipulate human DNA - and a simple visit home becomes a fight for survival.

Doctor Who continues its game of spot the homage. [This] story is an enjoyable synthesis of She, The Fly and The Quatermass Experiment - even down to the final battle in a London cathedral. But despite some charming interplay between the two leads and an excellent turn from Mark Gatiss as the young and old professor, The Lazarus Experiment is a pretty conventional runaround, though the nightmarish Identikit creature is superbly realised and dedicated Whovians can look out for a "reverse the polarity" reference.

I've been looking forward to the Doctor and Martha's return to the present. Two years ago, a slight miscalculation returned Rose to a point 12 months after her disappearance and not 12 hours as the Doctor had thought. What will happen here, with Martha and her family?

I'm looking forward to seeing Mark Gatiss in Doctor Who as well. He's a talented actor and writer and I'm betting he was overjoyed to finally get the chance to be in Doctor Who itself and not just a comedy sketch in 2003.
