The entire premise of the show is that a camera has a rotating platform with multiple stages on it that morph and change so that they bleed together and because of the way that the stages move around the camera, they can create scenes which create really neat optical effects using practical spacial relationships and forced perspective. It sounds highly technical (and it is to a degree) but in execution, it's simple, effective and unique.
The big fallout of the pilot, though, was that the writing wasn't all it could've been. There's lots of room on HBO to get wild with the ideas all in search for a laugh, but it seemed the production was more focused on the 'wow' factor of the concept rather than provide real humor, which is sad because I think some of the writing was 'forced' in terms of trying to use the format more and they lost their focus and primary objective which is humor.
However, it's worth watching simply for the spectacle and it makes one wonder how great the show would have been if Joel and crew had been allowed to get past their growing pains. I for one think it definitely would've found it's footing within 3 or 4 episodes and the focus would be on humor and the delivery via the creative concept would just come naturally.
But we'll never know and that's a real shame.
