Yeah, this season seems to have a different vibe to it, may just take a few episodes to adjust to it, but it definitely threw me off. Plus I don't know how they're gonna make up for the lost Pam/Jim tension. There were some parts that I found really funny, but they seemed to be more subtle, and I can't really think of any specifics.
What I thought would have been interesting for this season was if they began to air episodes of the documentary within the show, and show how the characters react to being on TV, like in that special of the U.K. version.
