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.
