All considering, it was very well done

Rating: 9/10 (7 April 2018)

Having read the book in advance of seeing the movie, and the book I consider to be a sci-fi masterpiece, the best sci-fi novel I've ever read, I was very impressed with how well it was condensed from a huge story into a 2 hour movie. Fantastic film work from start to finish. Very entertaining.
And if you enjoyed the movie, you should definitely read the book. It presents a similar but different version of the story with way more character development, a far deeper plot and will give you around 10 hours of entertainment.
