The movie was pretty dark. It shows how in a split second your life can change. You can do everything in life right go to MIT, be sucessful and happy but in a second God can take that away from you.
I don't think the purpose of the movie was to entertain but to leave you thinking a bit about guilt, mortality, living life for others and actually following the law about texting and driving.
so all u needed was a movie to remind you of all that?
