This show can be fairly formulaic at times, it does seem to skate a thin line between "we're just filming ourselves talking" and "It just looks like that due to skill and subtlety". I don't believe this show should be viewed too negatively, It doesn't always have me in stitches, but it's at least a wonderful standard in its type of Television program. The Comedians COULD have been edgier, less apologetic and sharply exploratory of more serious or obscure issues and themes, but so early on I don't think that would really suit the format.
I imagine the interesting blending of different perspectives, comedic styles, would have confused much or some of the general television watching population, a confusing blur between parody/satire and "earnest" human interaction.
It really could have grow into something very beautiful, I personally believe clear enough audience feedback and articulation was an issue contributing to its demise.
