Its CGI and optical effects were seamless and the story was interesting, the setup of the film with his family was well done, and all together it was directed very well. My only complaints are that it has some issues with the script, it never gave time for the story to breath and I thought that the last 15 minutes were absolutely unnecessary and could of been done a lot better. But it was a really enjoyable film to watch. My favourite aspect of the film was the amazing production design, but that's not enough to praise this film and give it a higher rating than it deserves. My only complaint is the unnecessary scenes, but that's not enough to hate it and rate this lower than it deserves. So its a tough decision but I'm giving Interstellar a 8/10 for its interesting story, and the fact that it was very entertaining.
