Great show, but I do have some gripes.
1. Cassie and Adam never find out the truth about the curse
between them.
2. Adam never finds out about Cassie and the elixir.
3. Cassie never finds out the truth about her mother's death.
4. The circle never finds out about their parents'
senseless acts against the elders.
After watching the last episode, the show feels unfinished; like it's left me off on a cliffhanger. I wish there were a couple more episodes to squeeze these details in; the show would have felt more complete then.
