You said movie, so I assume show (and by extension, anime) works too. Because Trigun has the worst ending I have ever had the horrible luck to see. It was an amazing show, it really was: I loved every second of it up to the last episode. The first half of the episode was a recap of the entire show: stuff that anyone watching the last freaking episode should already know. Then it spends the last half of the episode ending all the show's deep questions, intense emotions, and engaging themes in... a short, simple gunfight. No questions answered, no closure obtained, just a short fight with little to no dialogue. Beyond that, they even refused to tie the loose ends after that! Just... sigh...
