Any good?

It is...The acting and writing are solid and it is generally entertaining.

The premise is a documentary, with interviews from some of the characters in the "future" etc. And it generally works. Particularly becasue they don't treat the documentary crew as if they aren't there, the crew is sort of its own character. They even have impacts on the plot from time to time, which is a really nice touch.

My only issue is that occasionally it suffers from split personalities. Half the cast is in The Office. Half is in The West Wing. It isn't a melding of the two really, it is one show for part of the episode, and the other for the rest. Now this isn't a terrible thing, because both halves work (even though they focus on their "Dwight" a bit much) but it just feels like the two could be blended better.
There is also a dark cloud hanging over the show (at least for me) which is set up by some of the future interviews that seems out of place, or just to add some sort of gravitas to everything.

But in general I am enjoying it very much, and the performances are all solid, with a couple of major standouts.
