This week's episode of Doctor Who was a perfect example of being careful what you wish for. I've always wanted to know what was through the doors of the TARDIS. However, whenever we've had a peek (during Tom Baker's run, particularity in Logopolis, or more recently in Neil Gaiman's episode) what we've seen has been a bit of a disappointment - usually endless identical corridors or, on one occasion, a run-down Victorian swimming pool.

Unfortunately despite moments of brilliance, and a few beautiful sets, this once did not buck the trend and was largely the Doctor wandering around corridors while being chased by a fantastic looking but poorly realised and fleshed out monster. Again.

Any fan of Poirot, courtesan history or 1920s buff would be horrified to realise a case such as that of Princess Fahmy Bey had passed them by. Centring on a French courtesan turned princess who shot her Egyptian prince husband at the Savoy, it is the mystery of the 3 shots and the not guilty verdict. it smacks of Agatha Christie at her most lavish.

Channel 4's documentary Edward VIII's Murderous Mistress (rather like The Spice Girls you have to nickname them all to tell them apart, Murderous Mistress, Married Mistress, Divorced Mistress...) lifted the lid on both the playboy prince's sexual preferences (let's just say from Wallis Simpson's fondness for exacting neatness and scolding letters she might have been nicknamed Mrs. Grey had she lived now) and the lengths the establishment will go to to avoid scandal. Making you wonder if public nudity is the least of Harry's misdemeanours.

After The Rings Of Akhaten I was really not expecting much from this week's episode Hide when Neil Cross's (who wrote both episodes) name turned up in the credits.

However, although Hide suffered from many of the same problems as Rings (a barely fleshed out and vague threat, a damsel in distress that the audience had been given little reason to care about, and a rushed ending) this time the story worked and the episode was an enjoyable, but not exceptional, romp.

After last week's one note musical episode Doctor Who returns to form with an ice-cold classic Who episode. Ice Warriors and a secluded location under attack? That's a Patrick Troughton episode right there.

Mark Gatiss(sssssssssss) continues to be one of the most consistently entertaining of the new Who writers and this is probably his most accomplished episode to date. He's clearly a fan of the show and introduced a vintage foe to a new generation of fans in a tense, occasionally terrifying, Alien inspired episode.

The episode was on a much smaller scale than last week, pretty much a bottle episode filmed on a single set, but what a bottle it was! The submarine set was incredible, down to the sound effects and the constant dripping water. I've seen films with less impressive set design. Doctor Who may have had a massive budget cut but it isn't showing on screen.

Well that was huge disappointment of an episode. Without a doubt the biggest misstep of Moffat's era and on a par with Fear Her orLove And Monsters as a contender of the worst episode of new Who.

Most disappointingly it starts so well. The opening five minutes showing how Clara's parents met were beautiful. This was followed by Doctor Who's valiant attempt at a Star Wars Cantina scene, which really showed off how good costumes and CGI can be on a (reduced) TV budget. Sadly all the imagination and care that went into the visuals were wasted on a bland, pedestrian episode with a nonsensical dull plot.

Well, I did say that Richard E Grant was somewhat underused in the Doctor Who Christmas episode and now we know why...

Doctor Who returned to the screens this weekend with a strong episode that balanced humour, drama and fear and still managed to have introduce the new companion. Again. But this time it looks like we've finally met the real Clara.

This episode functioned very well as a reboot for the series, presumably designed to attract new viewers who have heard about the upcoming 50th anniversary. There were references to the past - I particularly liked the Jammie Dodgers and the fez - but the episode worked very well at introducing a new, slightly changed Doctor and explained exactly who and what you could expect from the two hearted alien this series.
