Where to start? This movie is so flawed, it is difficult to know which aspect deserves more blame.

First the music is actually very annoying. Repetitive and grandiloquent, it gets on the nerve of the listener especially after the first two hours.

Second, the characters are completely flat and uninteresting. Their emotions feel mechanical, and the 'bad' characters simply act erratically, as a function of the need of the story.

Third, the dialogs are full of platitudes ("love cannot be measured", says the astrophysicist) or outright absurdity ("gravity can travel through time"), and become laughable at times.

The worst is clearly the scenario. In addition to Marx brother's physics (relativistic effects without relativistic velocity, 300m high tides on a planet with 20 cm of water), goofy space exploration (you land first and then, you start thinking about what kind of planet it is), the plot spirals into such a pile of nonsense that it is difficult not to feel insulted.

Apparently, a good physicist was hired to provide the visuals for the black hole. It would have been also good to hire a scenarist that can write a story.
