I have to give this movie a big thumbs down. It was lacked the technology that it should have had. The Port hole that was the "Main Viewer" for the Nautilus was opened by Hand using a hand crank of some sort which I thought was hilarious that a submarine that could travel thru time would have something that had to be operated by hand...Many other flaws but I will let you decide..I am a Sci-Fi fan so I gave it 2 stars
