...that had such a horrible ending that it ruined the whole movie for you?

Again - and I honestly can't say this enough times because this is really the crux of ALL of this - people define their own entertainment. What is entertainment for one will not be entertainment for another. Some folks like MMA. Some folks find it disturbing. To some it is entertainment, to others it is not.

So - for you - you are entertained by the game win or lose. You want to see that game. For some folks, it is not entertainment they enjoy if they aren't winning - perhaps not winning every time, but winning enough to feel good about continuing to watch. You can't tell people how to be entertained. Just like they can't tell you what you have to be entertained by either.
