Culture clash comedies are nothing new, and in his new film "Vengeance," writer, director and star B.J. Novak heartily embraces the culture clash formula. But what makes this surprisingly rich and textured movie stand out is the collection of other influences that helps define it. It's a black comedy. It's a murder mystery. Parts of it have a Western flavor. Other parts feel like a neo-noir. It has a can't-miss satirical bite while also offering some timely commentary on the Red State/Blue State divide that's not-so-silently ripping our country apart. The movie isn't overtly political. Instead, it's interested in how we as Americans burrow into our own groups and are quick to judge anyone who doesn't fit within them.
