I watched this eight-episode show over the past few days and find myself with very mixed feelings, mostly leaning to the negative side. The premise: a stay at home mother (Marcella), who is a former police detective, has returned to active duty after a murder that fits the M.O. of a serial killer case she worked on years before. The twist, so to speak, is that Marcella is an unstable character, prone to blackouts where she does things she can't remember. Possibly terrible things that compromise the case she's working on. On the plus side, the cast is pretty good, led by the excellent Anna Friel as Marcella. Friel is what holds all of this nonsense together really, while the rest of the actors provide solid window dressing. Individual scenes work well, and it's artfully photographed. On the preposterous side, in just about every episode there's a red herring which is never resolved, just left to confuse the viewer and distract from the plot. The complex web of supporting characters is introduced matter-of-factly without explanation, which has the effect of keeping you on your toes (good) while also adding more confusion (bad). And the blackouts range from being a critical source of tension to a lazy out for the writers who clearly can't be bothered to think of a resolution for certain situations. In all, this could have been a much better show if someone with a strong editorial sensibility had trimmed the silliness out of the script and pushed the writers to think a little harder. I could almost enjoy it without thinking very much, but once it's over the problems kept nagging at me.
