The presence of so many ideas is, however, also a double-edged sword for the movie. While just a couple of themes approached are interesting enough, the film ultimately offers two times as many as needed. Perhaps it’s more realistic to find the future dizzying then have the luxury to just explore a few. Either way, it doesn’t benefit the film when we reach I Am Mother’s third act. While the goal may be to give audiences the kind of hit in the head Interstellar or Arrival does by the time they reach their twisty conclusions, the execution underwhelms in this outing.
