I found it interesting, though the inconcistencies in the character design bugged me to no end, and I thought the whole subplot with the captain's little brat and wife could have been dropped. Plus I found those mega-carriers to just be too rediculously huge especially since they were suppossed to be submersible. I love a good sub movie and for the most part this one was, filled with interesting sub designs, I just wish we got to see more of those designs.
