I don't know, Garfield still has his moments. Perhaps not as grand or consistently as he once did, but he can still get a smile, if not a guffaw out of me.
I think things did pick up when they shook things up a little and brought Liz and Jon together. They really should have built on that momentum. I'm not saying change who the characters are-- they haven't, really-- but new situations begets new material, and I think that's where the comic most needs a shot in the arm.
