Why do you rate using clocks rather than stars?
A long time ago we realised that we could tell how much a person liked a show by when / if they checked the time. So if someone checks their watch 10mins into a show there’s a pretty good chance they’re bored / not enjoying the performance. Likewise if they check the time 10 mins before the end this often means they’ve really enjoyed it and are hoping it won’t end soon. So, put simply, the sooner you check the time the worse the show is likely to be. So we represent how good we think a show is by clock faces. The more clocks, the better the show.
