It's legit a good movie. It's not like Chinatown good, but it's an entertaining film that does an excellent job with a low budget to make cheesy fun ala OJ Simpson chase. There's not much to it, the film is based entirely on dialogue, it's all characterization and it sells. There is no real action, the plot can be summarized in a single sentence. You're just sitting back getting to know two characters in a car, and, really, the two characters are amusing enough where you can listen to them talk for about an hour straight and not get bored with it.
