Though it certainly wasn't the first time a film has offered a little extra for audiences during or after the credits, Nick Fury talking to Tony Stark about the Avengers Initiative in 2008 kicked off the industry's current obsession with the post-credit scene.
While this can be used to tease the future of a franchise, give a little glimpse of what's next for a character, or take a beat for one final laugh, it does feel as though adding such a scene has become more of an obligation or expectation than anything else. Too many post-credit scenes feel tacked on, but then there are those that aren't just worth sticking around for, they are actually the best part of the entire thing. It seems insane that the height of the film would come when it is technically over.
Some of the entries on this list are bad movies that ended on a high note, either with a joke or a phenomenal set up for something further, while others aren't even bad themselves, but just ended on the high note.
