It sounds a little like going to watch Les Miserables except that instead of Jean Valjean coming clean during the trial of the man who is accused of being him, Jean Valjean sits silently by and lets the man who is guilty of other crimes go to jail for him. Then Valjean lives happily ever after. Speaking for myself, that is not the type of movie plot I would enjoy watching.
Maybe you should actually 'see' the movie before you decide what kind of movie it is.
Because you clearly don't have a clue.
Did you see the movie? What you are describing is not even close to the message portrayed in Crash.
