I was so disappointed in this movie as I LOVE epic sci-fi /hell, it doesn't have to be epic), but it was a decent concept that was just so clumsily cobbled together.
1) The Earth disaster story was just intensely lame (dust blight, because that's much cheaper and easier to film while still maintaining a backwater town feel, they probably saved millions of dollars there) and the transition from there to space too jarring. Where was the sense of scale? Were the oceans bare? Farmlife all dead? You had no real sense of tragedy or devestation. It was weak.
2) The script is AWFUL. In some places I literally could not believe how bad some of the lines were. The Love transcending space speech was awkwardly written and delivered. It just felt like the actors really didn't believe in what they were shooting, it just was not done convincingly, especially with Matt Damon who was possibly the least comfortable i have seen him.
3) Anne Hathaway... completely annoyingly portrayed and engendered zero sympathy with Dr. Brand. Her actions on the planet, and during the "lets vote for which planet next", were just stupid, and completely out of sorts for the situation and her profession, regardless of the love theme they tacked on to her role.
4)The robot... oh god the robot. Apparently, someone decided that in the future it would be a great idea to have an impractically locomotive robot with sharp angular edges (great for space suits, right?) that has about as much articulative ability as a forklift truck. Or at least it would have, had the designers not made it suddenly and improbably move about 100x faster than its design would ever practicably allow. It was kind of cool to look at, but also amusingly ridiculous.
5) The music was awful and grating, as well as too loud. It did not suit the on-screen action.
6) The plot in general I found sketchy at best. The last 40 mins were just groanworthy. I mean really, humans that are now so successfully advanced that they can exist in 5 dimensions want to now change time and stop their millions of years of evolution? And this space pilot, after being away 90 years, can just hop in an unfamiliar ship (that looked like a tiny scout ship, can't imagine range or robustness was so amazing) and pilot it out of the space station without raising any alarms? Please, arrgh.
7) Some of the special effects looked ropey... the black hole folding in on itself especially looked too artificual.
I love science fiction, I love good movies. Hell, as long as a movie forces me to suspend my disbelief then I even enjoy mediocre movies. This did not succeed on any front that I can think of barring the occasional nice set piece of visuals.
4.5/10 (yes, really).
