People disappointed? What would you expect???
I am not sure why people would go to a movie which is about a guy lost at sea and expect anything different?
Of course they will have the storm scene and
Of course they will show the usual issues re water/food ...
(Nothing abut bathroom etiquette)
And it really all comes down to the end: Will the person be found or not...
So then it becomes an issue of how the lone person deals with the situation...
I do agree with others that Redford almost had no emotional reaction but maybe this is his upbringing or the fact that the camera crew there made him feel better ...
But it did seem like overall, the movie made a point of being the FIRST movie with NO words spoken ... which did seem a bit self-serving...
