CSI: The Complete Series vs Longmire: The Complete Series

Buy CSI: The Complete Series if you want the bigger, better-documented set: 93 discs, 244 hours, widescreen, Dolby Digital 5.1 and English SDH subtitles. Buy Longmire if you prefer a modern Western with a tighter, character-driven story and a strong 4.6 rating from owners. CSI is the broader procedural catalog; Longmire is the more focused drama.
