You might be fooled by the names of Willis and Weaver that there is a production-value, decent story, excitement, humor, or suspense. Well, rest assured none of those exists. I'm sure Willis and Weaver got fat checks to put their names on the movie and the producers got their money's worth by using their box office draw. Save yourself two hours of your life and do some crossword puzzles instead--you'll have a more exciting and satisfying time.
** SPOILER ALERT ** The formula for these movies is that the hero finds a love interest who supplies sexual tension, here that person ends up being the half-sibling and kills that possibility.
