Watched the first 4. It's mostly about a middle/upper class family that owns a resort and the relationship between parents and 4 adult children. There are nasty skeletons in the closet that are slowly being revealed. There are a couple things that bother me about it but on the whole it is quite good. There is probably something that will remind you of your own family.
Just finished. There's a nice setup for season 2. If you like heavy drama then this is highly recommended. Good performances, good plot, all that shit.
