There are many films, books, games, etc. that are quite good, or even extremely good, the entire way through, but then are let down by a bad ending. Now, whether this ending be too short, too anti-climactic, too predictable, too far-fetched, too rushed, too cheerful and happy [that you eventually start to feel that it's overkill, and actually get angry] , too long and dragged out, or just poorly executed in general, they all have the same effect. You're left either unsatisfied or with a bitter taste in your mouth. But, unfortunately, so many stories suffer from this.
So, here's a place for you to discuss what you feel to be some of your least favorite endings.
