So next week we have Mark Gatiss' latest attempt. For those who do not know, Mark Gatiss is a highly regarded writer (in nerd circles, at least) in the UK- he made his fame in dark-tinted comedy but has a sideline in horror and Victorian-era stuff. He's written some very successful comedy series,. some very good books and in fact he tried to get the rights to Doctor Who himself before RTD got the job back in '05. Gatiss might not have got the top job but he came right on board as a writer for the new series.
But Gatiss' Doctor Who efforts have not been as successful as many might have hoped. He started well enough with the third story 'The Unquiet Dead' (exactly his sort of era and style, that, though he himself had to be persuaded by RTD to put Dickens in it), which some regard as the first 'proper' Who story of the revived series, but since then... hmm.
We had The Idiot's Lantern- evocative name, interesting idea, but really did not work well and was not a popular story. He then starred as Lazarus in series 3 but got rather associated with the dodgy cgi in that episode. He then had a pitch for series 4 that RTD actively rejected (something to do with a museum and World War 2 I think).
Then Moffat brought him back for... Victory of the Daleks. Oh dear. And to make it worse, he kinda bet the house on that as beforehand he was saying it's the best story he had ever done. As we know, VOTD is not exactly the most popular story going (and even amongst those who do not hate the redesigned Daleks, not many people put it as a classic). The anticlimax after that story caused a large Gatiss backlash.
However, Gatiss still has that high reputation- and has recently collaborated with Moffat on the highly successful Sherlock series- again with that period style that is his trademark- and got a lot of kudos back for it. So whilst people's expectations are now wary, there's still the solid hope that this is going to be a good story. It is very Gatiss in style- dark shadows, creepy horror etc and the advance reviews are good.
(Though they were good for VOTD too...)
