Looks somewhat promising at the beginning when the viewer keeps on guessing whether it is a psychological thriller or a supernatural mystery tale. The last episode goes rogue, the plot derailed, Capaldi plays Hannibal Lector tricks and the female protagonist descends into a hodge podge of what is supposed to represent time loops, warps, kairoses (Greek term for cracks in time), superimpositions and other D-level student's delusions about old Albert Einstein's theories. Waste of time in my book.
