Numb3rs: The Final Season on DVD includes all 16 episodes in a four-disc set. The audio is available in English in 5.1 or stereo with the option for English subtitles only. The aspect ratio is 16:9. The video and audio quality are both on par with previous seasons released on DVD, including a bombastic audio during the opening and transition scenes.
The special features include: "Coming Full Circle: Numb3rs The Final Season" an overview of the series as a whole, "The Women of Numb3rs" which explores the lovely, intelligent and quirky ladies of the show, "Pixel Perfect: The Digital Cinematography of Numb3rs" for the more technically orianted viewers, a production photo gallery of the cast and crew over the years, and insightful cast and crew commentary on three episodes (sadly, down from the amount given in previous DVD sets).
Thought I'm sad to see it end, Numb3rs had a great run. They probably could have squeezed a few more seasons out of it, but it may not have kept the same intensity, enjoyment or originality. I'd rather the show end on a high note, rather than fading away into something boring and horrible. The final season, thankfully, delivered a satisfying conclusion to a fun series.
