Watched this last night. It's kind of disturbing, but unique and I think will be unforgettable.
It's a tragic love story, certainly not a comedy.
Kind of in the vein of "the Pursuit of Happyness", which although brilliant was a definate 'downer'.
I won't give away the plot as you spend half the film wondering who is this man and what has he done? Particularly after he 'flames' a blind meat salesman, played by Woody Harrelson, over the telephone.
Not a happy story, but one well told. Will Smith is well cast in this role, in that I can't imagine anyone else doing an equal or better job.
Worth watching, unless you're dying of some illness, or have a phobia about box jellyfish.
