This is an excellent ending to Unbreakable and Spilt. It has been a long time coming and if you didn't watch the first two and just watched Glass...well you ruined it for yourself.
Unbreakable was a real thriller years ago. When Dave (Bruce Willis) takes out the murdering psycho at the end of the movie in a scene that seems to take forever, you begin to understand M. Night's story telling style. He doesn't do 'normal' hollywood endings.
Well done and hats off to a long awaited conclusion.
