Poseidon was a pretty good movie in general. I have never seen "The Poseidon Adventure," so I have no idea what it compares to. It was action packed and kept me guessing, it reminded me of "Day After Tomorrow" so if you liked that one you will like this one. I'll warn anyone who is scared of fires or of seeing dead people not to see this or at least to see it with someone who will shield your eyes from those parts. Poseidon is not a knock off of "Titanic" it doesn't have a love story in it. It's about the obstacles people had to get through every step of the way to get off the ship. The ship capsizes fairly close to the beginning of the movie, so it is obvious that the movie is about getting off the ship, unlike Titanic.
