How The Office lost its way

Jim used to be the loser everyman that never got what he wanted.  So when he mocked everything around him, when he couldn't take anything or anybody seriously, when he acted like he was better than everything, it was endearing.  He was well suited to explore with us this silly, absurd world filled with its bizarre characters.

But now that Jim is with Pam and he's happy, it's not so fun to watch him act like he's better than everybody else.  Now, it's just smug.  Perhaps, too, we've learned more about the other characters in the office, and now that they're interesting and funny, it's not as fun to see somebody act like they are all beneath him.  But mostly, it's no longer a loser smugly and indifferently mocking everything around him.  Now it's a happy, contented person that just arrogantly acts like everybody around him is idiotic and small.  That's usually the character we dislike.

Or maybe it's just not as funny anymore.
