Sequel Bait

G'mmm, that's a good cliffhanger!

When a franchise ends with something that screams "This ain't over!". UnTrashes that could lead to this include seeing that the Villain isn't truly dead, The End?, or leaving you with Exactly 8.3 Million unanswered questions that will eventually get answered. When a franchise Sequel Baits its audience with this UnTrash, that could get them excited for more of it unless they're aware of the possibility of a Sequel Curse. This could also upset the same audience as they believe the story ended perfectly with no Loose Ends or One-Way Questions.
