The Video:
Season one was shot in black-and-white, and its Blu-ray presentation looks quite good for the majority of the runtime. While the black an white grading never finds anywhere close to the rich contrast and dynamics audiences might be growing used to seeing on high end black and white UHD/HDR releases, the SDR grading here certainly offers a good foundational presentation of the content, with serviceable grading through the range, decent blacks, and adequate whites. Texturally, the image is fine. There are some softer shots and instances of grain spiking a bit, but overall it's more or less consistent in its filmic output and well capable of capturing good textures and fine clarity to faces, military uniforms, and various odds and ends both around the base's exterior and in the barracks proper. There are some spots and speckles here and there, but rarely do such things advance to such a degree as to become a bother. In fact, much of it is very clean and nicely filmic, with pops and speckles at times more of a rarity and less of a commonplace consideration.

Seasons two, three, four, and five were shot in color. The show also looks very good in color as well. It's tonally distinct, of course, and the show's tenor takes on a slightly different feel, but it quickly feels like the show's home once the jarring transition settles in. The image retains a very nice and filmic appearance. Grain is fairly consistent in density: more or less light but very much in evidence. The result is a very sharp, clear picture that is wonderfully detailed, right down to the finest dents on lockers and other small details and definition on various surfaces and objects in offices and elsewhere around camp (and other locales throughout the rest of the series as well). Of course, the image soars when it comes to close-ups of faces and clothes, which are brilliantly detailed to a nearly tactile level, showing fine scruff and pores on faces and intimate qualities and characteristics on clothes. The color is very good, with the notable green military fatigues a standout. White undershirts are crisp, skin tones are healthy, and black levels are very good indeed. The color seasons are also home to the odd spot and speckle, but there are no serious print issues and no encode problems of note, either. Fans are going to be delighted!
