This was my actual last straw with IMDb... I guess you have to like this one or else. And by that I mean they are purging all the bad reviews.
So, this is a movie about pretentious people, for pretentious people, that are killed by pretentious people so they can walk away feeling deep.
From the start you know what is going to happen, because it's basically the same thing that always happens on ominous deserted islands... and the "they eat the diners" thing was removed because one of the couples were regular diners there.
It sort of gives you only one plot direction made clear by the fanaticism of the cult of cooks.
So there wasn't any guess work that needed to be done, and from the start you knew which character was going to live because the broadcast that with a giant arrow pointing down at them.
But, hey, it's the modern audiance, nothing can be subtle today.
