It's fine sci-fi schlock. There's a likable cast, a few tense body horror moments, and an interesting idea with a disembodied arm. The mostly generic hodge podge of a script doesn't live up to the potential of the rest of the elements. However, the most glaring flaw is the B-plot, Earth scenes added thanks to test audiences, which doesn't have any bearing on the principal story that happens in space. Thanks, test audiences.
Putting Roy on a space station might sound like a bad idea, but making this movie was even worse. The Cloverfield Paradox is a rushed copy/paste job with not enough time to glue the events together. A bit of Alien here, a splash of The Philadelphia Experiment there and a handful of other classic sci-fi flicks sprinkled on top. Oh, that bit in Evil Dead was funny, lets have some of that too! Wrap it up with a title that attracts the horror people too and it is time to cash in the mockbuster it is.
Netflix. Don't go down this road. Let it end here.
