The first couple of seasons were absolutely brilliant but by now it just feels as if they've run out of good ideas and are going through the motions.
I get it, it's a successful show and they want to keep pumping it out and hauling in the cash, but without the overarching story moving forward, or glacially when it does, these episodes feel slow and ponderous.
I'd like them to accelerate the main story but obviously if they do that then it will end, and we can't have that now can we?
Even the language is less imaginative and amusing than it once was.
It's still OK, better than a lot of other shows out there but that's more an indictment of the industry than praise for this show.
They should wrap it up and end with dignity rather than whimpering to a dismal and quickly forgotten end.
