People keep saying that The Office should end when Steve Carell leaves.  Nonsense.  Personally, I can't wait for him to leave.  Oh, sure, a few years ago I would have thought they'd be crazy to have a Michael-less Office.  But if there's one thing that the past few seasons (especially the current one) have demonstrated, it's this: they don't need him.  In fact, they'd be much better off without him.  The entire cast has grown so much as characters (not to mention numerically), that they've outgrown Michael Scott.  Sure, Carell is still good at what he does, but at this point the character is just holding everyone else back.  Michael Scott is done.  He's a joke that's been killed from overexposure.  There's just nowhere else for him to go.  He's exactly the same as he was when the show began, and he'll always be exactly the same.  All he's doing now is getting in the way of the best ensemble cast on television, comedic actors who are brilliant at what they do and make it look effortless (especially compared to, say, Community, which I watched last night for the first time since the pilot, and which has a group of comedic actors who clearly strive mightily, and yet still aren't funny).
