If you're a keen cinema-goer, you can probably name one or two movies whose endings left you feeling a little empty.
Well, imagine what it would be like experiencing that feeling nearly every week - because that's pretty much the reality for fans of professional wrestling, where meticulously built storylines frequently climax in low-key or just plain confusing ways.
We should be used to it by now, but sometimes it's hard not to be hooked in by a feud between two wrestlers who have never before crossed paths, or a fresh, new direction which could open up the door for something truly exciting.
There're too many things that can go wrong though. WWE writers can misread the fan response, one of the key wrestlers involved can suddenly take their ball home with them, and perhaps worst of all, it can simply turn out that what they had in store all along was just bad.
And the result is a set of conclusions that leave a really bitter taste in the mouths of the fans who were so invested in it in the weeks or even months leading up to them.
10. The Wrestler
After the success of Floyd Mayweather's appearance at WrestleMania XXIV, WWE seemed desperate to get another celebrity in the ring at the following year's event.
As luck would have it, a Hollywood star of considerable profile had just released a movie in which he played a professional wrestler - and, what's more, he was apparently prepared to step inside the squared circle for a taste of the real thing.
Fans got excited (well, some did anyway - most just got annoyed) at the prospect of seeing Mickey Rourke face Chris Jericho at WrestleMania 25, but those dreams were dashed when it was announced that his handlers wouldn't allow it.
Ricky Steamboat proved a more than serviceable replacement, despite his advancing years, but the storyline itself just didn't work without Rourke lacing up for real.
