I am completely baffled by the current IMDb rating of 8.8 for this film; it’s hard to fathom. I certainly didn't enjoy it very much. The narrative isn't compelling, the science is absurd, and the visuals aren't particularly striking. Perhaps they would be more impressive in a large cinema (I watched it on my home theater system, which has a fairly big screen by European standards), but I’m not convinced of that either. Please be aware that what follows may contain some spoilers. The movie begins with the familiar and tiresome "told you so" scenario favored by environmental activists set against a backdrop of a dying Earth, immediately establishing a depressing tone. It feels like an overused concept these days. Then they pile on with a school official claiming the Apollo missions and moon landings were fabricated. Seriously? If their aim was to depress the audience from the outset, they certainly succeeded – at least with this viewer. The plot moves forward as our protagonists discover gravity waves in the sand, which they then stretch the bounds of imagination to interpret as coordinates leading them to a secret NASA base. Once there, Cooper is informed that he's their ideal pilot for a mission intended to "save humanity" via a wormhole. Right! This guy used to work for NASA. His whereabouts couldn’t have been unknown to them. If he was truly the best choice, why wouldn’t they have contacted him sooner, instead of waiting for him to stumble upon their operation? It's classic Hollywood nonsense! The movie is riddled with this kind of absurdity. Romilly spends 23 years doing practically nothing except deciding against entering a sleep capsule. The supposedly highly trained and screened professor they locate turns out to be both a psychopath and an idiot, nearly destroying the ship while attempting a docking that all systems indicated had failed. They then proceed to dock with the main vessel, stop its rotation, and propel it out of orbit around a planet using the shuttles’ engines. That's one incredibly powerful shuttle, not to mention the strength required for the docking mechanism! This just keeps happening. Whenever someone isn’t doing something illogical or foolish (or both), they are engaged in lengthy conversations, philosophical discussions, and slowly advancing the plot. 169 minutes is far too long for this movie. The film ultimately descends into a convoluted time travel mess (although technically they aren't traveling through time, just sending messages backward, it’s still…). This occurs during a series of psychedelic scenes while traversing the black hole. Science? Not really. And what about that completely ridiculous, massively illogical, and inefficient robot design? The one positive thing I can say is that the performances of most of the actors, particularly Matthew McConaughey, are quite good. Otherwise, it wasn’t for me.
