I give it a 5 only because it is an overly sentimental at times, ludicrous in its storyline, bloated sci-fi attempt at landing the Nolans some Oscars. A manipulative almost-dross. Chris Nolan is simply too ambitious for his own good. The comparisons with Kubrick's 2001: Space Odyssey are demeaning to Kubrick, they are not in the same league as film directors. Kubrick pandered to the intellect and treated viewers with respect, Nolan panders to the American Film Academy and the box office, and treats viewers with disrespect. Kubrick was a film artist, Nolan is a film craftsman and a businessman, nothing more. Interstellar contains too much talking, too much exposition. One astronaut explains to another the basics of how black holes work, like to a little child and just moments before they are to enter one? Pleeease. And what's with this father-daughter love and bond, crazy and all? The crying and weeping, she breaks into a crying fit more than 20 years later (kid you not) at the thought that daddy might have deceived her?? The underlining thesis of the film is that "love is the only thing (a "thing"??) which overcomes time and space". Corny and retarded, and so very Hollywood. Emotional and family-oriented string-pulling is at the core of Hollywood filmmaking business, that's what makes them mega bucks, so they go on manipulating. Chris Nolan is either emotionally infantile or a manipulative hack, a film artist he is not. Basically the only element in the film that I liked very much was the music score, I found it very pleasing and strangely not overbearing, though there is a lot of it in almost every scene. Even the much-praised special effects and shots of the cosmos do not impress, for me there is not a single scene that gives a feeling of enormous vastness of space and how the Earth is but a tiny, little speck like a grain of sand on an ocean beach. I guess the film will be nominated at least for special effects and musical score, but it is far from a masterpiece.
