is a hard science fiction film that relied on renown theoretical physicist Kip Thorne to make it as scientifically accurate as possible.
The first two hours are overall a pretty good film. The Blight, wormhole coincidence, and higher dimensional aliens are acceptable extreme fiction to work with a drama taking a more realistic look at humanity facing extinction and asking what it means to be truly live instead of just surviving. The science aspects felt more like background, but worked with the story because they were not as fantasy as other sci-fi shows like Doctor Who
or Star Trek
Then the weird stuff started happening. Theoretical physics relies on mathematical models to try to guess and explain how the universe works. None of it has yet been tested and you can sometimes have competing, but equally valid theories or it could all be wrong. Many of the ideas of theories come across as alien to most human reason that it is no different from magic. And sadly that is what happens here.
The sudden introduction of a tesseract, time travel, humanity's future decedents, and love somehow being quantifiable and a basic part of the universe is jarring and pulls you out of the narrative. If feels like it moves out of the genre of hard science fiction to Science Fantasy
. The ending itself felt rushed as if the director realized how long the film was becoming and needed to wrap things up quickly.
It is a welcome chance from the Science Fantasy
films that are often found nowadays and is a good exploration of human drama in this setting. However, it could have done without the last twenty minutes or so that get into too much of a mind trip that it takes the viewer out of one genre and into another. This is no way a bad film, but out of recent realistic science films I liked Gravity
