I was really disappointed, considering all of the great actors involved and since I love science fiction and the great disaster films of days gone by. I bought the DVD used and got my money's worth--it's a decent watch.
I would recommend watching if you like disaster movies or any of the actors involved, maybe even renting or buying the DVD used or for a really good price new, say for 5 bucks, but anything more would be wasteful or being ripped off.
