well, coming back from jumping the shark in Norn Iron in the tird series the fourth series was wonderful, hopefully 5.6 and 7th will be likewise, talked about here:

I agree that the Norn Irn bits of S3 were the point of shark-jumping only because after that it was all downhill.
Didn't it jump 12 sharks in the s4 finale? People say that it did.
