A large and capable cast is thrown into a spiritualistic western, with very little character development being it's most obvious flaw. You can tell the bad guys from the good guys, but care very little about the outcome. There is nothing wrong with attempting to mix genres, however after a bang-bang beginning, "Purgatory" grinds to a slow crawl for the middle thirty minutes. The ultimate confrontation is nothing more than a prolonged, tedious gun battle that you have seen many times before (pick any western). More dialog between the combatants would have benefited the movie, especially the Eric Roberts and Sam Shepard characters. Somewhat unique, but still nothing more than a marginal missed opportunity. - MERK
