No, I do understand you and I appreciate that if you've already spent hours watching the show, you might now be getting to the point where the characters are revealing themselves. However, I've gotta say: that sounRAB like a huge investment of time for (IMHO, other views are valid) a very small reward - one that you can't even have known about when the show started, since it's only happening at the end of the 4th episode.
Further, now that their personalities are being revealed, they appear pretty dam' lame. I acknowledge the earlier point that this is supposed to be some sort of "human story" but that's not to my taste either, it's simply not entertaining - and yes, I have read Pinter.
I don't need TV to show me human stories, or the tragedy of a mundane existence, I see that every day. Putting it on TV and calling is "comedy" does not validate it, or somehow make it worthy or insightful viewing.
