TVguide.ca uses bubble factors (
) and star ratings (
) in our Fall Preview reviews to help viewers decide what to watch.
Bubble factor: Used to rate if a returning TV series is on the bubble and will/will not fold. One bubble means not likely; five bubbles means you may want to try a new show.
Star rating: Used to rate how well a new TV series will fare. One star means it probably won't survive; five stars means it should last awhile.
