I gave this film a 7 due to its technical, acting and CGI innovation and brilliance, but cannot recommend it as anything other than attractive theoretical masturbation. It was great entertainment, but that is all that it was. No story could be much further from reality than this one was.

As a scientist viewing it from a purely scientific position, the absurd theory and its execution in this story would be approximately akin to one postulating then expecting that "pregnant cows sent into space would give birth to pigs and then return to earth as puppies water skiing behind porpoises".

The above postulation is almost as absurd as this film story was, but maybe not quite. Leo is now one of our great American film actors and did a great and convincing job in his role, as did the entire film for extracting great reviews from people who know absolutely nothing about real science, but sure do love loud and visually exciting and bombastic stories of extreme pseudo-science. However, my scientific training and experience would not allow me to join them in that fawning praise even though I did like Leo and the CGI work a lot. Human reality and truth are too crucial to me to ever become a fan of such utter nonsense, no matter how attractively presented it may be. Perhaps that may be my loss, but so be it.
