This show is about Science Fiction with some Drama and when you watch one episode you fall in love with the characters: Max (Jason Behr), Isabel (Katherine Heigl), Michael (Brendan Fehr) and Tess (Emilie de Ravin). They came from the space crashing of a UFO. They have secret powers and live like normal people but looking for answers and trying to understand who they are, why they are here on the Earth Planet.
The plot is so amazing that you can't be bored and keeps you wondering about the next episode.
The show also had an unforgettable soundtrack.
It's a show that is so unique that you can't compare it to anything. It's a pity just have 3 seasons.
