For Scientific Validity, please watch Carl Sagan!

Rating: 8/10 (3 October 2015)

From my point of view, most of the users' reviews have one thing in common; the search/demand for scientific validity. What on Earth? Have we forgotten how it is to enjoy a film without grabbing a scientific book? The film is great and anyone can watch it with pleasure. Of course there are "holes" in the script, inaccurate scientific dialogs etc. But hey, tell me a film that was all the way accurate (except maybe from "2001: A Space Odyssey").
You can find scientific holes in a bunch of sci-fi films: Matrix, Avatar, Interstellar but they were all great films Take for example "Avatar". All the big living things (like the Direhorse) on the planet Pandora have six legs! Sorry but you cannot run when one leg is just beside the other! It is orthopedically wrong. But still I love the film.
So my opinion is this. Enjoy the movie.
