Not really worth watching if you are expecting a level of genius as put in movies like shutter island or inception.I was able to predict most of the show not to brag or anything. Nice one for kids though i would say that for sure age 12-15 maybe. If you really r seeking a really good thriller/suspense I would recommend you Sherlock (Benedict Cumberbach). Best one I had ever seen....and no way you can really figure out the succession unless of course if you really are a genius.
