As has been stated I do not understand why this movie is rated so low other than I suspect it is from people who are not into the whole submarine warfare drama. As a big fan of Crimson Tide and U-571 this movie really scratched an itch I have had for quite a while now. I thought the cinematography and action sequences especially the explosives were excellent. I also enjoyed the combination of the seal team mission with the drama playing out on the submarine. The only reason I am not reading the movie higher as I thought some of the casting was a little off. I had a hard time excepting Common as an admiral. He did not seem old enough to be an admiral and just seemed out of place the whole movie. I thought Gerard Butler did a decent job as the Captain of the Arkansas but I had a problem with him trying to cover up his Scottish accent. I also thought there were a few holes in the plot such as how they were going to get the sub back through the minefield even if everything went as planned. However none of it was significant enough to spoil the movie as a whole. The funny thing is something very similar to this almost happened when Boris Yeltsin was president of Russia. I could easily see the US having gotten involved in helping to defeat the coup attempt made against him.
