You can never get enough of seeing James Nesbitts wrinkles acting their little hearts out. This was ludicrously unbelievable, but that doesnt mean it wasnt thoroughly enjoyable. Just dont analyse it too hard (if at all)... i mean if you did, you might question why the perpetrator didnt dump the bodies straight down the shaft, rather than carting them 100 yards down a foul smelling sewer, or why carlton couldnt get out of a car boot for 2 days, or why Barbie danced rather than just got on with it
