Reid has what appears on the surface to be an Internet arranged blind date at an upscale restaurant with a young woman named Cat. It is, however, a supposed business date, with Reid pretending to be a potential client for her, one of the Dirty Dozen assassins, she the "Black Widow" of the bunch. In a break in the case, the team has determined that there are four assassins, all working independently, but acting like spokes on a wheel to a central axle, that axle being someone code named the Snowman. However, she, being good at her job, knows that the meeting is a set-up. When Reid and Cat come clean to each other, what results is a thirty minute game of psychological cat and mouse between the two. The outcome is affected by how well Reid and the team have Cat profiled, how well she in turn has calculated the strategic moves in their chess match, plus a little, or perhaps a lot, of what Reid just went through visiting with his mother on his recent time off from work.

Best episode of Season 11, bar none
14 August 2016 | by TheLittleSongbirdSee all my reviews

And this is saying a lot. Most of Season 11 has been disappointing, being average at best and poor at worst with only three or four episodes being good ("The Job", "The Witness", "Beautiful Disaster"- am aware that this is a controversial opinion- and especially "Entropy").

"Entropy" is by far the best of the season, and the only one to be close to a masterpiece. Would even go far to say that it's one of the best episodes of the latter seasons along with "Mr Scratch" and "Nelson's Sparrow" and one of the best of the whole show.

My only small criticism is Cat being outwitted a bit too easily and outwitted somewhat, but to me this was easy to overlook because the ending was still intense and moving (her line about her remembering Reid's name and he not remembering hers chills the blood and makes one feel so sorry for Reid) and because the rest of the episode was so brilliant.

Usually Lewis is an underwhelming character and Aisha Tyler's acting impresses even less, but Lewis is much more at ease and pretty bad-ass and Tyler gives quite easily her best performance of the season, at least to me.

What was immediately fantastic was the story. Loved that it was centred around Reid, who is one of the show's most interesting characters and whose absence during the hiatus was immediately noticeable and instantly deeply felt and the episodes that the hiatus concerned suffered heavily as a result amongst many other things. But it also doesn't neglect the rest of the BAU or what makes 'Criminal Minds' so good in the first place, which so much of Season 11 lost or forgot about.

There is tension, suspense excitement, emotional impact, humour, twists and turns, chess-like manoeuvring and ingenious verbal sparring galore, the writing and storytelling really is some of the finest in a long time. The chemistry between Reid and Cat is truly a joy, the episode provides a truly satisfying conclusion to the Dirty Dozen story arc, Reid is developed absolutely beautifully here and the sight of Garcia drunk is priceless.

As ever, "Entropy" is incredibly well-made, hauntingly scored, tightly directed, majestically paced (one of few of the season to be rushed or dull) and as said the writing is the best of 'Criminal Minds' in years. The acting is the best it's been in a while too. Matthew Gray Gubler is phenomenal, and playing one of the more memorable supporting characters of Season 11 (cool, calculating, confident, deceptively charming and subtly chilling) Aubrey Plaza matches him brilliantly.

In conclusion, Season 11 has never been better, and along with "Mr Scratch" and "Nelson's Sparrow" it's one of the best latter season episodes. 10/10 Bethany Cox
