See it. Very good movie. No slow spots and a coherent story line. Big props to the US Navy on this one. It had elements of Red October and the plot could have easily been taken from a future incident in our present climate. Gerrard Butler played a great character and actually contributed to the production. He's come a long way from King Leonidas. Again, you like hi-tech thrillers? You want action beginning to end in 90mins flat? See this movie and just enjoy it... Even the wives and/or gf's will like this one. Cman
