The cgi is great. The concept is too much like Captain Ahab and the white whale. When they get boarded by pirates—well it’s a bit ridiculous. After all this movie is supposed to be in the future by 130 plus years so why not have more firepower against such invaders? A ship hunting such a large “dragon” should have guns enough to blow the pirates away. It’s an ok movie but glad I didn’t pay to see it in a theater!
