Such is the fate of The Cloverfield Paradox, a stunningly well-cast sci-fi based on a Black List script, which seems to have undergone so much re-tooling, at every stage of production, that it barely resembles a completed film. There are plenty of ideas on display here (literally: the film crams in quantum entanglement, meeting your doppelganger, outer-space espionage, an energy crisis, mind-controlling worms, and more). But most of the concepts are hurriedly introduced and then abandoned, leaving behind an experience that feels like a generic mashup of every sci-fi release from the past thirty years.
