Like a basset hound coming in first at the Kentucky Derby, Richard Linklater’s Bernie is a floppy, improbable triumph. Nothing about it should work, but almost everything does. Essentially the story of a very friendly murderer (Jack Black), Bernie poses a finely balanced ethical quandary: What do we do when someone we like does something terrible to someone we hate? This isn't a documentary, and Linklater isn't constrained with balance or objectivity. Your opinion will shift, at times in sync with and in times in opposition to the film. Films this challenging are rarely so pleasant about it.
