I was about 30 seconds into the first scene when I knew that something was terribly, terribly wrong. Everything about this third series of Fortitude is off. The first thing you notice is peculiarly misjudged performances from actors who were fine in the previous series. Then it becomes apparent that the direction is haphazard and the overall tone is strangely off. Pretty soon it's clear that the script is poor. And it's not long before there's no escaping the fact that the series has, sadly, jumped the shark and strayed beyond bizarre into utterly ludicrous. They really should have quit after Series Two. It must have been apparent to everyone involved that series three wasn't up to scratch . One can only presume that it was already too late to simply show some mercy and pull the plug. It certainly would have been a better option than trashing the brand completely.
