This movie is not his masterpiece. I actually like Nolan's movies such as Memento, The Prestige and The Dark Knight Trilogy. But this movie is too long and dragging it seems like waste of film to make a movie this long. Why input lots of useless dialogue or scenes? The only part I like is actually the part they're not in space, as the effect on space is not really good and gets a little boring overtime. If I want to watch a movie with space, I prefer and suggest to watch Cosmos: A Space TimeOdyssey (2014), it have more awesome visual stunning effects than this movie and also more clever approach for your brain because it teaches you REAL science.

Maybe Nolan is not ready to make a Space Movie. If you think this is the best space movie of all time, I suggest you watch the Alien (1979) and Aliens (1986), Star Wars and Star Trek franchises, and 2001: A Space Odyssey (1968). I prefer Hal 9000 over Tars for an AI.
