When I started watching the show I liked it a lot as it was a good story and they kept it interesting by having viable convolutions to the story. I also liked it because Margarita Levieva is a good actress and needs to get into more TV shows and films.
It started to go downhill quickly in the last few episodes just because characters behaved too irrationally, and they decided to change things that didn't seem to be happening before.
I would have liked to have seen how a season managed to play out and see how some of the characters are developed more so then they were originally. But, unfortunately, I can understand with the last episode or two why the show was canceled as the show lost its focus.
