I have so far watched every episode from the first five seasons and about two thirds of season six. I have found that the show is good but by season six, the quality had dropped a bit. Sure, some of the shows were very good...but too many seemed like they had just run out of ideas...and "Out of the Night" clearly shows they'd run out of ideas. It's a bad episode mostly because they have Peggy doing stuff that simply makes no sense...none whatsoever.
When the show begins, someone Peggy knows has a child dying in the ER because of a drug overdose. Now understand, ALL of Peggy's friends throughout the series either die, are accused of a crime they didn't commit or have disappeared...so being one of Peggy's friends or their family members is a very bad thing! However, what happens next is just nuts. A detective recruits Peggy to go undercover to infiltrate the drug trade! She is to pose as a prostitute...and inexplicably, she almost immediately is recruited by a drug contact...and it just happens to be the same one the cops have been looking for and don't know the identity of until Peggy just walks into it!! And I know this will sound mean, but Peggy just doesn't look like a prostitute* but like a pudgy middle-aged mom (when you see her in a bikini, you'll unfortunately see what I mean). Now had they played her as a housewife who needs money for drugs, it might have worked...but a $350 a trick prostitute...not likely. What follows is one near miss after another for Mannix and Peggy...all the while she DOES have a son waiting for her to return.
The bottom line is that the show never makes sense and the infiltration works way too fast and way too easily. I think the show has, by now, jumped the shark and I only hope that it regains its solid footing in upcoming episodes.
*Sadly, in real life Gail Fisher DID become a drug addict once the show was complete.
