I have never been more disappointed with a movie, as I had such high hopes.

Many others have gone into the flaws with the story, non-sensical science, and poor dialogue and I generally agree with the harshest of those criticisms.

But I'd like to add one that isn't being said much: The film is mostly blurry (a few scenes were sharp so it can't've been the cinema), and whoever maintains the lenses forgot to clean them as there's specks and hairs (again, it can't've been the cinema because they varied between the different scenes). If you see it at an IMAX and have good eyes, this might bug you. In my opinion there's no gain in seeing it on a big screen, as it looks like it was shot last century.

Nolan's wrong, film-cameras suck (Just compare the image quality of Interstellar to, say, the Hobbit movies and you can see where movie technology should be heading). Also, this is exactly the genre of movie that looks best in 3D. (And to those who don't like 3D: Just see the 2D version).
