The worst part was probably the story. It is very obvious, every little twist that is. And I don't just mean that Vash isn't dead. If that's a spoiler for you, you're just strangely not aware of the likelyhood of the main character of a large franchise dying before the movie is even close to over.
Following that, would be the original characters. Like in many films, they lack even the interest that you would feel for a character who was introduced for one episode or chapter of a manga.
Lastly was the music, which while fitting in some ways, was rarely used and not put to good use.
The pacing was also strange. Like many movie adapations, it forgoes most character interaction for extended scenes of nothing. Also, planet gunsmoke now has 3 moons, which I don't personally recall. It also has a very populated galaxy, which again I don't recall. There's like 20 planets on the zoom out, all within a planets distance of each other!
Of course, Vash was made out to be an idiot, rather than just somewhat strange.
While the animation was really good, it just lacked most anything that made Trigun good. And I did watch it subbed, unlike some reviews for it that rated it rather high.
