I started to get annoyed at binging a TV show only to have it end on a sour note. It struck me that when that happens, people that rate the show on sites like IMDB will rate the final episodes below overall trend of ratings for the show. So, I can use the wisdom of the masses to know if I should try to watch a TV show.
I pull down the IMDB voting stats and calculate the trend-lines for TV shows.
Each bar represents an individual episode. It's showing the 1 to 10 star user-ratings for that episode. I should point out these aren't strictly "average ratings", but rather a weighted rating. This means, at least in theory, things like "vote bombing" and other collusion attempts are accounted for. In theory.
The colors are only to group different seasons, they don't mean anything.
The straight yellow line on top of the ratings is the trend line for the ratings. Basically, it's attempting to show how the show's ratings change over time. A flat trend line means the show's ratings might go up and down, but on the whole, they stay around the same value. A trend line that goes up or down means that on the whole, the show's ratings go up or down. The blue line shows the popularity of each episode.
Great! Let me know which show, I'm curious to find edge cases where it failed.
Perhaps in the future, but right now I'm focused on TV shows.
