I've just finished watching the first episode, which I found to be excellent. As others have mentioned, something this original and ambitious is amazing, and the video itself is HOT!
(SPOILER ALERT)
Things that I especially liked:
* The over-the-shoulder shots in the mud and during the chocolate gunging, which were something I hadn't seen before anywhere.
* The dip Meg took in the first part of the video, which felt fun and spontaneous (kind of weird to say that for a planned thing, but that's the word that comes to mind). Meg sold that part in particular very well.
Things that I wish I'd seen:
* A true shower scene in the wet part, as opposed to three different tub scenes
* PIES!!
* More of that caramel sauce that you guys have in Proper Messy. The chocolate is nice too, but it's so dark that it can leave the models a little featureless.
(END SPOILER)
Anyway, as a whole I thought it was awesome, and I want to congratulate you guys (esp. Meg) for such an excellent start.
