20 years after it was released, I finally watched Tin Cup. The climatic scene was so improbable, so false, that it killed the movie for me. Spoiler Kevin Costner hits a perfect golf shot and lands a 3-wood about three feet from the hole. It rolls about 18 inches closer to the hole, before inexplicably rolling backward, off the green and into the lake. The problem is that shot rolling to the hole ... 18 inches away ... would never turn around and roll the other direction. Now it's obvious that I take my golf a little too seriously, but it baffles me why anyone would make a movie where the climatic moment simply couldn't unfold in the manner they portray. Anyway, it killed that movie for me. If you have another example of a movie ending, climax, or scene that left you shaking your head and killed the movie for you, feel free to share the agony.
