Twice as Dead

I've seen road movies like this before and they always fall apart. This started a little loose -- who are these people? what's with the bickering? -- will they please wise up -- and then instead of falling apart it comes together. The reason for the bickering starts to matter. They grow on you and grow on you and pretty soon you're laughing and looking forward with a groan to the next bonehead move. It's a movie built of "oh-no"s and that's the fun. It deals with human beings and their frailties, the damage failed dreams causes, the suicidal cement of disappointment. I saw it in screener form and don't know its availability but if it becomes available it is a strong recommend.
