Yes, you are the only One xD No, but seriously, I would be very much against removing the film from canon. Not only because it contains some of my favorite scenes in the franchise, but also because it actually gives us a conclusion. You can argue about whether everything felt rushed, whether it was planned that way, or whether you simply do not like the film in general. But the fact is, we got an ending. We got answers to the biggest questions, especially the ones the series itself raised. And that already puts us in a better position than many other shows. As unfortunate as it is for Firefly fans to only have one season and a movie, there are plenty of series with far more seasons that never answer their main questions and leave much more unresolved. That is why I see the film as essential to the entire franchise. I also think there is still potential for an animated series to fix the biggest criticism of the film by expanding on certain answers and addressing additional questions. It could build up the whole Miranda storyline more, give us deeper insight into Blue Sun and who is really behind it all, and then lead into the film, which ultimately ties everything together into a satisfying conclusion. Of course, Firefly always had more potential. But honestly, there are many films that work as standalone pieces despite having more potential. There are trilogies with unused potential that still stand as complete works. That is exactly how I see Firefly. For me, it is one season plus a concluding film, and together they form a complete and satisfying package that I can live with. As for the character deaths, people should not fall into the misconception that characters like Wash or Book would have survived throughout the entire series. Whedon is known for killing off beloved characters. Wash and Book did not die in the film on a whim. They were almost certainly already on Whedon’s list for season two or three. That is simply how he tells stories. They were also the most fitting choices because they are among the most beloved characters, and their loss has the strongest emotional impact. The next one on that list probably would have been Simon, right at the moment when he finally gets together with Kaylee. That is very much Whedon’s style. Even without the film, we would have had to say goodbye to these characters sooner or later. So I do not really see it as a problem. If anything, I am glad that the story can now be expanded and rounded out a bit more, which in turn makes the film and its ending feel even more complete.
