Query: This is a dumb movie; don't waste your time watching it

I like ship movies. This one was just a big waste of time. Bad acting by every member of the cast, flimsy story line. After about 15 minutes of the movie, I realized that I would get just as much out of it if I watched most of it on "fast forward". I wish I could sell this or get my money back from the person I bought it from. The original Poseidon Adventure was enough. It did not need this sequel.
