I realized that most of Christopher Nolan movies has this problem. At the beginning idea and plot is intellectual and intriguing. But at the end it turns into a very ordinary and simple story. At this movie it turns into a simple father-daughter story. I guess that's Nolan's way of making a lot of money. But i have to say that cinematography, sound design and compositions were awesome. If you like stuff about space, you can give it a chance. Or you must. If you haven't watched this movie yet you must be living in a cave or something.
