This was a great series & I wish that at the least it would have gone on for 21 episodes. Most of the episodes were a little boring but towards the end it got interesting.
Christina becomming totally evil was a surprise to me & Jesse betraying her by trying to kill her when he almost had the good Christina back was another surprise. And that's why she became evil.
There were alot of loose ends, but they managed to tie up the most important things in this series.
It also would have been nice to see Christina's father during the finale.
