First, it isn't clear Xavier: Renegade Angel will work in a movie format. The show is fast, and I don't know how they can stretch any single idea out to 90 minutes. Second, Xavier causes catastrophe. He pretty reliably destroys whatever town or state or planet he wanders to within 10 minutes. If you blow up the planet in the first 10 minutes, where do you go from there? Third, it will cause the heads of any viewers to explode. This will cut down on repeat ticket buying and DVD purchases from movie viewers, which means financial failure for the project.
