Glad to see the return of his quirkily excellent black comedy. First two episodes shown tonight, then 2 more each night through to Thursday. Or get it all on All 4. May watch tomorrow night's episodes as aired but may not be able to resist binge- watching the final 4.
I've watched it on Catch up and I'm not quite sure what to make of it. Perhaps you need to have watched it from the very beginning as Ken has suggested.
