Well, I think that...
...(Jesus Christ, how did you misspell "you" twice in a row?)...
...These categories of endings are way off. You can have a compelling ending that goes on "Happily ever after" or a shitty ending with a sappy "Victory through hardship" spouting crap. Also, it's funny how there was "TM" after the Happily Ever After, because you might as well put it after all the other choices as well. They're all have the potential to be original or horribly cliche.
This is no different than saying "All good action movies have guns in them." It's a pointless and utterly wrong assumption connecting two irrelevant concepts.
