My word. There HAS been some exercising of minds hasn't there over the just-over-half-way-point-Who episode. Comments got very excitable about wasps using lead piping. Paul Fuzz duly - and wittily - slapped 'em down a tad for kinda losing the point [even if MediumRob advised him that way danger lies].
Anna loved it. Marie loved it. (Though both with qualifications).
MediumRob was more qualified still - perhaps not helped by his antipathy to Agatha Christie.
There's been criticism that it was lightweight and dull, plenty that it wasn't a Doctor Who episode at all (really? I won't be the first to cite episodes from earlier DW incarnations that do similar cross-genere things).
What I thought:
Fenella Woolgar - gah, she's divine in this. Perhaps the most perfect bit of casting they could have managed (and even if Felicity Kendall WAS revealed to have been shagging a wasp, she too was beautifully selected for the role.)
Donna - with the magnifying glass. BRILLIANT. She was just fabulous in this episode and is proving the best challenge to many new Who critics in confounding their expectations.
Comedy - you didn't laugh? Shame on you! Okay, so I doubt I would go so far as to quip you being a 'humourless muppet' (for fear of offending Muppets - when DID 'Muppet' become a term of ridicule and abuse? I digress....), but it was funny! Yes, all those cross references to Christie stories were a tad wearing - just as they were in The Shakespeare Code - but there are worse traits to keep re-using [I may slap someone if they keep doing the 'talking in exaggerated way: the Doctor tells them 'no, don't do that''] Personally, I loved the 'Ginger Beer' request from the Doctor in his poisoned state to the hapless footman. An obvious gay reference joke? of course, but it was still pretty witty.
Gratuitous Marie-pleasing action - Lord knows after her recent criticism of him, I'm not entirely sure she deserved it, but there was some seriously lovely waspy-honey-stuff licking with glasses on. In a comedy Who episode. I don't think you can complain about that.
The Wasp - the only thing that hacked me off about the Vespiform was the utterly pointless (except for episode padding) death/not-death of Agatha when the Vespiform was about to die. Wasn't Gareth Roberts under on his Shakespeare episode as well? Didn't notice as much padding there as here - all the swirly fade-outs aside - but the moment when the pink bubbling light of the Vespiform seemed to be taking the life of Agatha with him as he drowned only for LITERALLY TWO SECONDS LATER it to change it's mind... meh. Seriously weak moment.
The Unicorn - apart from lending itself to the title, there really was no point to the thief was there? She was pretty though. Not much of a mystery.
The buzzing vicar - Don't know why I didn't guess it was him earlier really...
I liked it so much that - albeit by force of timing - I watched it twice. First by iPlayer and then (because it was bang on the start time on BBC3 when we'd finished doing that) on the TV screen. Thoroughly good fun followed by the end of Indiana Jones.
Shame we have the Euro delay after this, but I'm already freaking over the forthcoming Moffat-fest. Anyone NOT already afraid of shadows.... you will be.
