Runtime Patterns by Season
Season 1 episodes average about 53 minutes, with the finale at 62 minutes. Season 2 maintains a similar average (about 54 minutes) and ends at 65 minutes. Season 3 averages around 57 minutes across nine episodes, culminating in a 68-minute finale. Season 4 runs longer on average, with episodes near 60 minutes and a 70-minute finale.

Why Do Episode Lengths Vary?
Variations come from story needs, cliffhangers, and production pacing. Early seasons use shorter episodes to build structure, while later seasons lean into longer arcs and bigger set pieces, often ending seasons on extended episodes. Wider cinematic beats, character moments, and action sequences can extend runtimes naturally without padding.
Format and Platform Notes
Episodes are presented in standard widescreen (16:9) on Netflix, with Dolby Digital audio options. Runtime figures reflect the publicly released version; director’s cuts or early screeners are not included. If you’re planning marathons, expect slight differences if episodes are edited for syndication or regional platforms.
Planning Your Watch Time
Use the table above to estimate how long each episode will take. For example, a season-long binge of Season 4 will take roughly 9 hours and 26 minutes in total. If you prefer shorter sessions, target the mid-50-minute episodes in Seasons 2 and 3 for a more manageable viewing block.
