I watched this last month with my dad. It was ok, but younger kids might find it disturbing. it's about these people who are survivors when a ship flips over and need to find a way out. 8+, since i got a little freaked out when this lady was burned to death.
This movie was awesome!!! Although this movie is old, it has good special effects. If you are not sure about seeing the newer Poseidon, watch this one first. It's not as graphic.
