For the film critic, the problem with twist endings is that it is frowned upon to dwell on that final revelation, despite their importance to the experience. Even just mentioning that there is a last-minute information dump that causes us to rethink the entire film is often too much for the reader to handle. It’s a fine line to walk, but neither the critic nor the reader/potential viewer should be overly sensitive, particularly if it is made clear why such information is included.
