I'm quite enjoying NBC's version of the Office. I think it started out a bit milder and a bit less on target than the BBC version. There's probably no way Steve Carrell could really match the character created by Gervais in part because I'm not sure there is a perfectly analagous US archetype. But the writing this season has been really good, and the last show especially, with the fire, was hilarious.
Check it out if you haven't, and take a look at the BBC version also...
