Changes are in store for the men of the 12th Precinct in the second season of "Barney Miller", which is presented in its entirety in this three-disc, no-frills collection. Chief among the wrinkles to the show's proven formula are the departure of Gregory Sierra's Chano Amenguale, who would leave for his own series after this season; also, Barbara Barrie, who made a strong impression as Barney's wife Liz in the first season, would be relegated to the sidelines for much of this episode run before leaving the series, though she does earn her own storyline for the first and only time in "Social Worker." Otherwise, the second season is focused largely on Barney and the rest of the detectives (as most fans preferred) as they wrangle with crazed gunmen ("The Sniper"), a marauding rodent ("You Dirty Rat"), job insecurity ("The Layoff") and a punishing New York city summer ("Heat Wave"). Hal Linden's smart performance as Barney remains the glue that holds the series together, though there is excellent work from Abe Vigoda as Fish and Max Gail as Wojciehowicz, especially in "The Kid" (Fish becomes enamored of a pickpocket's mother) and "Discovery" (Wojo investigates police harassment of a gay couple). Series followers will also note the presence of future cast members Steve Landesburg and Ron Carey among the guest cast; both would join the show (as Detective Arthur Dietrich and Office Carl Levitt) in the third season. Video quality is a little worse for wear in certain episodes; the set also features two superfluous "mini-episodes" of "Charlie's Angels" and "The Facts of Life" as its supplemental features.
