Great Sci-Fi Movies That Don’t Really Make Much Sense

Some science fiction movies play by rules that feel slippery at best, and that is part of the fun. These films twist time, bend identity, or scramble causality in ways that invite viewers to piece things together their own way. You get closed loops, unreliable narrators, and realities that do not align neatly. Here are twenty five that lean into the puzzle, with each one noting who brought it to theaters.
