“Obviously I miscalculated a few things.”
You already know what path Limitless will take from the first ten minutes. And though the runtime does drag during the second half due to its predictability, there’s still merit to the film as we see a hypothetical outlook of how one might behave or think with greater capabilities. One pleasant surprise is an ending that doesn’t aspire to preach to us about the main character’s changes. While one could argue that Morra is a more or less flat character because of this, we do at least see some level of development, just not in an overly obvious manner.
