"GRAVITY" Falls Down, Can't Get Up

Pretty much the emotion felt for the whole of GRAVITY
(pencil sketch by me).

For a long time, I avoided seeing the film "GRAVITY."  Just about everyone said it was great and, usually when that happens, and I see the movie, it isn't great.  Plus, from the trailer, it seemed like it was a one Plot-Point-Movie.  I hate PPMs because I feel like the writers have made very little effort to construct an interesting story.  All they had to do was come up with one cool idea to strand a character somewhere or in some situation and then let what ever natural obstacles exist do their job.

There was a movie a few years ago about an attractive, white scuba diving couple who find themselves stranded at sea without a boat or so much as a piece of wood to float on.  I didn't see this movie either because I thought, short of flashbacks, how could this be anything but emotional-torture porn?  How boring and depressing to sit through something that can end in one of two ways.  They die or they don't.  The former being completely depressing and the latter being completely unrealistic.
