Watching this season I didn't know that the show was cancelled until I was at the second to last episode. At least the gave an actual finale instead of just ending.. To be honest I had decided to stop watching the show once the season ended.
About the season, to be honest the Sally/Aiden never think things through. Their continual mess makings were starting to become a dead horse.
However when it come down to the finale episode, I liked the way it ended. Not too overly sappy, Aiden/Sally, the two characters I felt that unreedamable from all the messes they've made and lives/souls they've destroyed, sacrificed themselves allowing Josh to get his happy ending with Nora.
