The stories are compelling in a way that sneaks up on you. But the real hook is in the crowd-sourced element that the audience guides the story. Knowing that everyone involved jumped into the story without knowing the ending makes the stories feel more dynamic, even the older arcs where voting has long closed.
Wonderful storytelling with a twist! The audience can vote for on the direction the story will go. Which requires a great deal of flexibility that the creative team doesn't get enough credit for.
And it's just as well performed as it is written! As a bonus!
