Welcome to this years SpoilerTV Cancellation PredictorLast year, each week, we updated our data (see the notes below about how we get our data) in order to see if we could predict which show(s) would be renewed or cancelled. As you can see fromlast years summary, we did pretty well. We're hoping this year to make it even more accurate.This index is by no means a 100% accurate guide about if your show is safe or in danger and should be seen as a bit of FUN.
