Let me spoil you (not really):
The series never gets good. It's just that you become so used to the characters that you eventually enjoy watching them walk through whatever stupid, nonsensical plot is laid in front of them. And I guess at least the characters are consistently portrayed.
But I was still facepalming in the final season quite a bit. It's an enjoyable series for watching in a group and laughing at or generally commenting on/blogging about (which you're doing), so I think you're all set..

You did indeed stab me in the back. However, you are only level one, whilst I am level 50. That means I should remain uninjured.
