The premise is an interstellar mission, species level extinction risk, first contact, scientific problem solving. The film frames this through cute banter, soft sentiment, and quips that shrinks the movie scale.
So it treats a genuinely huge science fiction premise in a disney type emotional level. The humor feels adolescent and tonally deflates the stakes. Instead of using first contact, isolation, and extinction level danger to create awe or intellectual depth, it turns them into a cute, reassuring buddy experience.
Bust fit Deadpool level jokes, with the first Alien humanity ever encountered? Really?
Plus the direction is bad, the pace is bad and Ryan Gosling I am sorry is no great actor who can talk to a rock for 2 hours and carry on a movie....Also it is not just a bad movie it is also bad Scifi, because it wastes the genre central strength meaning using speculative ideas to confront us with something bigger, stranger or more unsettling than ourselves.
You had everything....extinction of the stars of the universe, first contact, humanity in danger, a regular human trust into the most important project... but instead we ignore the scientific challenges, and logical problem solving who are by the way are a major part of the book.
And this is what I mean by Good Scifi vs Bad Scifi...
They even managed to squeeze some kind of half baked love relationship almost unrelated to the core plot for Ryan Gosling, that is so badly delivered and is so ambiguous... you almost wonder who is partner was, and what any of that had to do with the movie delivery...
They managed to turn an alien into a lovable emotional device. No wonder kids love it...
