Well I dunno, with the Office, it just isn't funny.... I don't think you wrap it up with different camera behaviors you wind up with a better show.
Arrested tried the "reality style" cinematography with scripted episodes.. and it really made it difficult to watch, even though the show was funny... the constant jumping of the camera nearly made me move on even though I enjoyed the show.. they toned that down quickly though, and kept the feel.
Well, that's your opinion. Have you actually seen the British version on BBC America? I think it's the best comedy in years. Many of the American sitcoms like Friends seem stale and formulaic by comparison because they have an army of script writers working on each laboured pun.
