9.1 at IMDb? Seriously?? 4 of my 5 stars are for the visual effects. 1 star is for McConaugh and Hathaway. The Nolan brothers, however, get zilch for their bullshit cosmology mixed with banal sentimentality and quasi-philosophy. It is a mystery to me, why some filmmakers love to mix so much "science" into their movies, when most of it is so horrendously unrealistic, misleading, incomprehensible and incorrect. Kubrick avoided most of the science talk, and created an artistic expression of the space-and-time mystery. That's why "2001" will remain a masterpiece and why "Interstellar" will be soon forgotten. And the movie is also painfully slow, 168 mins, most of which are spent on closeups of McConaugh and Hathaway, with or without space helmet as well as worn and rusty space equipment, as if that would make it look more real...
