I love it! I do think the show is at its best, though, when slightly more subtly showing us the humor to be found in mundane office life. For example, there was a cold open last season where everyone is in a meeting, and rather than focusing on Michael (who, for once, thinks he has an audience in the palm of his hand and runs away with it), they're all looking past him to the DVD screen to see whether the bouncing DVD icon ever goes directly into the corner of the screen. Sometimes I'm more amused by things like that than the more obvious laugh out loud moments. The British series is tighter and better-constructed on the whole, since the U.S. team are having to stretch things to generate so many new plot ideas.
I also like the comedy/tragedy dichotomy. At this point, I'm invested in poor Michael, whose insane behavior stems from a pathological need for approval. Or Jim and Pam, who after years of bad timing might actually have gotten it right. The British version especially could turn on a dime and take you from being amused or outraged to existentially depressed.
I haven't really noticed any type correlations among people who like it (I like it, my INFJ friend doesn't, I know ESFPs and ESTPs who do, etc.). If I were going to theorize, I might say that very strong Fe users might find the uncomfortable humor a little too uncomfortable.
