I saw the original 1972 Poseidon Adventure a couple years ago and I loved it. I saw this hoping that it just did the original justice. And I think it did. This version is about a cruise liner, the S.S. Poseidon, that has terrorists on board that intend to blow up the ship. They plant a bomb and the ship takes in too much water and it capsizes. Only a group survive and head to the bottom of the ship that is above water. The group is lead by Mike Rogo, a homeland security agent, and a terrorist that he captured. It includes many of the original characters in different names, and a couple added. The deaths in the movie are predictable and many of them are pretty weak, but overall, it updated a great movie.
