by Mike Krumboltz If the measure of a great movie is that it confuses, divides, and causes endless debate about "what it all means," then " Inception " may be the best flick to hit theaters in a good long while. The Christopher Nolan-directed film, about a man (Leonardo DiCaprio) who invades people's dreams to steal their secrets, has earned strong reviews from critics. But not everybody believes that the intricate (and confusing) plot actually makes sense.
