The Quality Arc
Each point is an episode, plotted chronologically. The colored bands mark season boundaries. Look for upward or downward trends to see if quality improved or declined over time.
Episode Engagement
Vote count shows how many people cared enough to rate. High votes + high rating = beloved classic. High votes + low rating = notorious stinker. Low votes + high rating = hidden gem.
Rating threshold:
36 Standouts
4 Infamous
9 Hidden Gems
29 Forgettable
Top Standout: S1E20 Chapter Twenty 'Five Years Gone'
Most Infamous: S2E6 Chapter Six 'The Line'
Best Hidden Gem: S1E0 Unaired Premiere Episode
Episodes plotted by rating vs. vote count. The vertical line marks the rating threshold (7.5). More votes = more engagement. Toggle above to compare against global or show-specific median.
Series Trajectory
A simplified view: one point per season. This smooths out episode-to-episode noise to show the overall arc of the series.
Season Momentum
Did each season build momentum or fizzle out? Green arrows mean the finale rated higher than the premiere. Red means the opposite. Longer arrows = bigger swings.
Season Consistency
Some seasons are reliable bangers. Others are hit-or-miss. Each dot is an episode. Tightly clustered dots mean consistent quality. Scattered dots mean a mixed bag.
Each dot is an episode. Clustered dots = consistent quality. Scattered dots = variable season. Hover for episode details.
