The hit rate here is high enough that skipping ahead never feels like an option.

For late-night viewing or a proper weekend binge, Justice League Season 1 fits the bill. It does not lean on comparisons to make its case. Short enough to finish in a weekend, substantial enough to feel satisfying. Watch for Kevin Conroy in particular — the performance elevates the material. Satisfying on multiple levels.
