In two separate incidents, an unsub has raped and/or killed in Los Angeles, California. The first victims, two females, were raped, tortured then killed in the downtown area. Three days later in the suburbs, a woman, in her home, was raped repeatedly in front of her husband, the latter who was ultimately killed. The wife was purposefully kept alive. These incidents have taken place in the area of the city where the rolling blackouts have occurred that evening, the blackouts to combat the excessive power use due to the heatwave. Garcia determines that the unsub has been at work for at least twenty-six years - raping and murdering during blackouts - the individual incidents never having been connected since he has never killed in the same city consecutively until now. In speaking to the detectives in charge, the BAU make a connection to one of the first killings as the reason the unsub has returned to Los Angeles. From there, the BAU think they know who the next target will be. They ... Written by Huggo

Solid finale to Season 5
29 June 2016 | by (United Kingdom) – See all my reviews

Since first viewing 'Criminal Minds' seven or eight years ago now, it became a favourite and while there are better episodes and seasons than others it still is.

While not one of the best episodes of the entire seasons, "Our Darkest Hour" for me is one of the better season finales of the show. As ever, it's stylishly filmed, very atmospherically lit with chilling use of darkness and lovely locations. The music fits well and doesn't undermine the tension in any way, with the theme tune still hypnotic. Who can't argue with one of the most effectively haunting uses of Leonard Cohen with "I'm Your Man" to grace my television set?

Most of the writing is solid, apart from a couple of inconsistencies and continuity lapses to other seasons (particularly with Morgan) and Morgan's dialogue at the end stretches credibility somewhat. It doesn't undermine the investigation in any way though, because much of the dialogue thought-provoking and with some nice tension and little out of place humour.

The story throughout is riveting, with very few 'Criminal Minds' episodes having as creepy an atmosphere (so creepy it's almost disturbing) and despite being only the first of a two parter it's always cohesive and the twist three quarters of a way through is very clever. The ending is quite intense, helped by the presence of Tim Curry's Billy Flynn and his dialogue, which is golden in how frighteningly twisted it is.

'Criminal Minds' regular cast are on top form, particularly Shemar Moore, and Eric Close and Robert Davi are good in supporting roles. The only "weak" performance is that of Isabella Murad, her performance is much better in the season 6 opener but she does come over as forced here and the terror that Ellie should have been feeling at that point was not particularly believable.

"Our Darkest Hour" however belongs to Tim Curry, who is skin-crawlingly brilliant as not just one of the show's most memorable and perhaps its creepiest unsubs but also his second most terrifying villain (even when not saying a word, even his appearance here unnerves you) role after Pennywise in 'It'.

In conclusion, solid finale though better was to follow in the second part of this two parter story. 7.5/10 Bethany Cox
