Loved the Luther series, so was really looking forward to this, but within 3 minutes started to doubt whether it was any good. By 20 minutes in, I realised it was so shockingly bad on every level (apart from Idris Elba) that I had to turn it off. Dreadful script tipping us headlong into high intensity drama before we've even built any sympathy for any characters; appalling dialogue; an odd plot with holes in it from the very beginning; patronising shlock horror special effects; and a very odd wig that expands and shrinks minute by minute. I actually had to check if we'd got to 1st April yet, as I thought it must be a joke. It really is THAT BAD. And has prompted me to write a review for the first time in my life. Good luck if you're going to try it, but you really shouldn't waste 2 hours of your life on it.
