Slither is a comedy but its the type that never clearly announces that it is one. You just better pick up on the humor in this series of bizarre events. James Caan plays a recently released prisoner who gets drawn into a crosscountry search for embezelled money. Which is made up of a number of strange episodes and all the while a mysterious black van follows. Some of it is amusing and it never stays in one place for too long. It's also a movie you'll find yourself asking "what's going on?" constantly. Not just because of what's intentionally obscured in the plot but even what directly happens is so strange.
