Agh, I hate that way of ending movies! They used to do it on lots of early X-Files episode, too. The Monsters of the Week are defeated, yay!... and then, just before the final credit, you get the sting in the tale, that glimpse of the Truth: they've not been defeated at all! I do not like that trope, and am NOT happy to realise that said trope has taken up residence in my piano. Grump!
