..... a plane crashes on a remote island and there are survivors and thats where the similarity ends. Each episode deals with the present time (NOW) and the island (THEN).
Every character cliche for any survival based series and movie is here. Add to this, that the characters are unbelievably dimwitted. It doesn't help that the acting of this group is atrocious. This sums up the THEN portion, trust me, there is no more depth to it than that.
On to the NOW portion, the only reason it gets 4 stars. The plot holes are numerous and the main actress is unintentionally funny. Bad acting but it was funny. One of my favourite parts is when there is techno music playing and the sister is at the computer. Cool, some hacking, this has promise. Then we see the computer, its just a search engine. Nevertheless, she still manages to pick up a trail of breadcrumbs the police didn't find. Ha! This is one of the smaller plot holes. Other stupid things like a girl who is badly beaten, with blood pouring from her nose is asked how she is doing and then veers into family drama, eventhough her captor is still there. One would think there are slightly more pressing issues at hand. This sums up the NOW portion.
The remainer of this series stumbles along a well walked path, with so called twists you can see a mile off. In summary, if you don't watch this, you won't get FOMO.
