The show has a lot of great qualities, however, there are some continuity issues at the end of season 2 jumping to season 3 and it seemed like the storyline was forced to move faster and felt rushed. I would have liked to see Peter's character expanded out a bit more. The shapeshifters and how they worked seemed to change and were not consistent. Peter figures out his father's secret in such an abrupt way but then cannot seem to identify Olivia's secret which is much more glaringly obvious, in my opinion.
Beginning of Season 2 we begin introducing a new character, then suddenly she is gone with no mention. Another show with written-off actors/actresses with zero explanation.
I enjoyed many episodes of this show but I would definitely not rate it above three stars. It is a so-so show with many fatal flaws. Still, it is entertaining.
