Little of actual import happens in either Downton Abbey: The Grand Finale or Spinal Tap II: The End Continues, two sequels – and theoretically climactic ones – to culturally beloved properties that happened to debut on the same day. (Had they arrived one week earlier, the films could've shared an opening weekend, and made an unofficial three-fer, with The Conjuring: Last Rites.) It's doubtful, though, that their fan bases will complain much.
