This silly movie resembles a spoof of Spielberg's classic JAWS. There is also a touch of POSIDON ADVENTURE and LEVITHAN included in the plot.It's mindless fun if you have 100 minutes to waste and don't expect too much. Fans of cool new digetal effects(sometimes obvious) will also enjoy this film. The DVD edition looks great. With fine, sharp colors on a wide screen image. A very listenable commentary by Samuel Jackson(often humerous) and director Renney Harlin, also short making of featurettes, trailer and still photo file are included. Quite a lot of extras for a dumb flick. DEEP BLUE SEA may be worth a rental, but only true fans will want the DVD.
